1. Infantry units walker animation should be slowed down imo. Looks ugly/kiddy when they move so fast. Speed should remain but animatyion slowed down. :p
2. Units firing sounds all the same and not a lot of difference even between playable factions there is 0 difference. More colors and others sounds should be cool.
3. Impact: Epic units feels like starter units. Sounds of them are not "HUGE" and firing power is silly imo. (Not the power but the visual power).

Maybe consider fix that for more impact & intense feeling when playing.
