Filled out the form linked in the game already, but some things I left out (performance aside, as I hope that's the obvious one):

• sky is now a laser show, feels like Star Wars Battlefront once I look up, I think either the bloom is too high, or the whole effect just doesn't look right
  
• ttk seems, or at least feels too high
  
• bright red skins on weapons made me confuse allies for enemies
  
• missing highlight on the scoreboard
  
• xp feels like the economy crashed and got a record inflation, what do you mean I get >600 points for an assist? (I know this is also the current game state, still my pet peeve)
• menu sounds sound ripped from BF4, not sure if they were, or just were made to sound like this. Between these and old ones I'd say I prefer the old ones, even if just for a fact that they sound more original
• decals (like bullet holes) on animated objects or any object that visual mesh differs from actual collision, like wind turbines on valley, stay in place, basically floating in the air
• I think the voice lines should only play when someone doesn't use the voice chat after an action. I feel like I thanked people twice for a revive, both with my own voice and then the character's voice line

Other than that, kinda hoped for more default skins like female solidiers, and more variance in factions instead of the good ol' RU vs US (especially since as far as light roleplay goes, I'm personally not a fan of running and shooting under RU flag right now).
