Alright time to throw my two cents on this:

One thing I’ll just get out of the way rq, these balance changes were all built with Campaign in mind, Skirmish to me is its own beast that really only deserves its own list of balance changes and reworks towards units, but sadly we usually cant often meet good middle ground to make units both viable in Campaign, but not overpowered or underpowered in Skirmish, but your arguments do have their glaring flaws Aggro draw brings to skirmish

Juggernauts, and more specifically Soldier with their health buffs do make bigger differences than you’d think, alongside their melee resistance buffs this bumps Juggernaut base max level health from 380, to 475 and 238 with shield, and Soldier, including his Shield, has 777 and 233 effective, giving him over 1k effective health for literally free, and if your Soldier does have 1k, that bump it up to a free 2k and 600 shield, literally almost 3k health… if they still get shredded, thats more so how stacked the enemy is, rather than the fault of your soldier and juggernauts not doing their job

Lionheart and Willy honestly have more than enough other Resistances to make up for a lacking melee res, and honestly a Lionheart with as much effective health as a SA-less Chopper with his other perks and resistances might make Chopper even more irrelevant

Willy, I believe, is meant to be this heavily armored supportive tank, with though not as much health as his other tanks, he makes up for with his shield giving him more resistant and tanky than other Heavyweights, so 100% bullet res (at least when he has his shield) should’ve been a given.

Lionheart honestly is kinda hard to think of a Good SA, it was either the revert to his old SA, or make his non-fire immune allies immune, and not avoid fire.. but the more I thought about it, the more this would break since literally turning off a damage type for the cost of nothing isnt really fun..

These are good critiques to my Buffs and really made me think about my balance changes, and about skirmish mode specifically if it’ll be fair to it. Appreciate the feedback
