lack of balance
The developers can't decide if they want a historical realistic game or a game game.
Hence the light tanks being overal terrible and not really useful for scouting at all because their real historical counterparts were just low tier tanks.
I'm like a 50% bittervet. On one hand I really enjoyed the game, on the other hands I became frustrated by a bunch of issues in the beta that persisted through out the whole beta. Which pretty much carried into 'release' (aka, start charging money for gold coins for the same game version as you were playing in the beta).
I feel there is a lot of untapped potential in this game. Like... gamemodes that are not random deathmatch
