You say the mercs that aren’t in the game are being balanced but lets be honest, the game was pretty well balanced before. Also HOW can you balance mercs without any data on them playing against the other mercs?
TBH we know your excuse and or reason for not having all the mercs out is all about your f2p model. We understand you are releasing mercs one by one with huge gaps so we will be more inclined to buy them with real $$ instead of spending 200+ games per merc. But this will end up working against you because this process will take way to long and also because if all the mercs aren’t in the game the mercs ment to counter each other and the balancing will be off.
Just release all mercs in like a $30-$40 bundle and then you can start actually balancing the game.
