They could balance this game in the first try.
Blizzard balance starcraft’s asymmetrical races in the first try as I don’t see a lot of patches. This is a RTS game
For non RTS games, if this game is patchless except for new levels, then SD pulled off balancing asymmetrical teams for the first try.
Correct me if someone else has made team games with asymmetrical sides that was already balanced on the first try.
I know WoW failed at that because their first few patches was for balancing issues and they had to remove the Dwarven Mage.
