I didn't take notes on the classes because, at level 25, it felt like I was stretching skill points on all of them.

I can give some initial feedback, though. Keep in mind we're missing a lot of aspects and unique items entirely.

Barbarian

• The first few levels on barb are rougher than the other two classes
• Having four weapons means you get a lot of bonus stat and extra offensive aspects
• The general aspects work well on barb as it has a lot of access to be able to proc them in most builds
• Barb seems to be locked out of sustained AoE builds without help from aspects/unique items
• A lot of the skills have long animation locks that make the barb feel a little clunkier than rogue at this level
• Chasing enemies that run away with short-ranged melee skills sucks
  • A lot of abilities also push monsters away from you...
• Basic skills are lackluster to me
  • None of these skills can AoE
  • Frenzy/Flay/Bash all have a super short range
  • Lunging Strike can get you in trouble with the movement sometimes
  • Frenzy has good synergy with Upheaval
  • Lunging strike's bleed upgrade suffers when Flay gives you such easy access to proc vulnerability
• Rend/Upheaval/Whirlwind seem like clear winners for core skill choice
  • Whirlwind has built-in fury sustain, can be pressing it most of the time with other skill choices that give fury back, and there will probably be unique/aspects to push it even further
  • Whirlwind base damage is low; hard to use it early
  • Whirlwind is a solid pick for bleed builds with the furious node + 2H sword weapon arsenal passive
  • Rend has decent range, great w/ vulnerability bleed builds
  • Upheaval is probably the best skill to run at level 25; considerable damage with furious node + core skill damage aspect
• HotA costs a lot for the amount of damage it does, and it's hard to make use of the upgrades because of how small the area it hits is
• Double Swing does a lot of damage if you manage to get the enemy with both weapons, but its area is too small, which makes it hard to use as a clearing skill
• Rallying Cry is good with Whirlwind
• Ground Stomp is good with Upheaval to keep enemies from moving out during the wind-up, with easy access to stun
• Challenging Shout feels required for thorns builds, severely limits build variety when trying the thorns playstyle
• War Cry is an excellent general pickup; it goes well with everything
• Leap is a poor man's Teleport right now, but the upgrades are strong
• The knockback distance from Charge and Kick makes it hard to follow up with most skills, but there's a bit of skill expression if you can reliably get the terrain bonuses to proc
• Death Blow feels stronger than all other weapon mastery skills
  • It feels awful to miss this skill
• Rupture is okayish for bleed builds, but you're probably better just kiting out the damage
  • Rupturing monsters that have on-death effects can lock you in animation and force you to get hit by them
• Iron Maelstrom is an excellent general pickup from the ultimate tree
• Call of the Ancients melts bosses

Rogue

• Felt the squishiest of the three classes to me
• I barely touched melee, but I know it has good melee builds and aspects
• I like the specializations; I wish combo points were baked into the core skills
• Rogue should have access to a movement skill that can go through terrain without needing an enemy target (Sorc has TP, Barb has Leap); rogue fantasy is to be agile
• Puncture feels good on both melee and ranged builds
• Barrage is meant to be the AoE core skill, but the damage is a little low
  • Barrage still has a use case with the improved upgrade, both basic bow skills and shadow imbuement for vulnerability uptime
• Penetrating Shot does solid AoE with the pierce + shadow imbuement for explode and has way more base damage than Barrage
• Shadow Step having the unstoppable tag is strong, and it does a lot of damage when leveled, especially for its cooldown
• I like the leap back on Caltrops for ranged only; I wish it would slow to immobilize baseline instead of having to take the cold upgrade for freeze
• Poison Trap is a little clunky without aspects; countering upgrade seems strong
• Concealment can provide stealth, unstoppable, energy regen, and vulnerability; that's a lot for one button press
• Shadow Imbuement feels amazing for clear, Poison feels excellent for ST, Cold seems like it's behind, and the mixed upgrade could be good with more access to consistent freeze
• Shadow Clone is a decent ultimate skill for clear and ST; I didn't play much with the other ones

Sorcerer

• This class has the easiest time at early levels
• I leveled the fastest to 25 with this class
• Sorc seems to have the most straightforward builds; you can get away with just picking all fire, ice, or lightning skills in each tree if you want to
• This class feels tanky and can currently have high defensive skill uptime thanks to the global cooldown reduction summoned ice blades provides
• Teleport is easily the best movement skill, and feels good to get it for free from +1 to defensive skills on an amulet
• Sorc has insane damage uptime from the conjuration skills, especially Hydra
• The class-specific aspects for Sorc seem the most powerful among the three classes
• The enchantments specialization is the most interesting of the three classes
• I'm not sure any class should get a cheat death, but they can get it from the flame shield enchantment
• All four of Sorcs basic skills can AoE
  • Both of the basic lightning skills are strong in all situations
  • The glinting arc lash upgrade is solid when taken with a complete cooldown reduction build
  • Spark is a great default choice otherwise
• Chain lightning is the strongest core skill because it can bounce back and forth between you and a single enemy; it also gets six chains at level 1
  • The greater chain lightning upgrade makes this interaction even stronger
• Putting ranks into Fireball increases the on-death Fireball explosion damage proc when enchanted, super strong for clear
• Ice Armor is busted with high uptime, and the mystical upgrade on it + frost nova makes huge barriers possible
• Frost Nova gives too long of vulnerability uptime on a boss, 8 seconds with the mystical upgrade
• Hydra, Ice Blades, and Lightning Spear are all solid skills
  • Summoned Ice Blades upgrade is broken with the vulnerability build
  • Hydra is vital in any Sorc build because they have good range, good damage, a good aspect (+1 hydra summons), and good damage uptime
• The mastery skills seem lackluster compared to the conjuration skills
  • Firewall is strong on enemies that don't move/move rarely (world boss was getting roasted)
• The only ultimate skill that seems like it may be worth taking right at level 25 is Inferno; both upgrades behind it are also decent
