If the devs of Battleforge had that opinion then Battleforge would had never get any balance patch ever. Because when the Juggernaut would be able to kill every unit with 2 strikes and you find that unfair and cheap and you dont like him because of that, then dont use him Right? PvP would be an mess, if new Cards are too op and you dislike the braindead playstyle of that, dont use this op Cards. Of Course you will lose probably every PvP game if you dont use this crazy op Cards. Because everyone would use powerfull Cards over lame Cards. But hey if you dont like them dont use it!
Who cares About balance, dont Change any Card please. Lets make the game just like you remember as an kid, it is unfair if you could not use your favourite op Cards and make more useless Cards more viable. You are used to that Card it would be an Miracle if we would implement more tacticts that would increase diversity. Lets just Keep everything like it is now, i mean Change is bad Right?
