It should be "childish" to them because this game is 9+, 9 year olds are stupid enough to buy it based on the ads.
The average kaw player is older than 9, for sure. Maybe theyre trying to get more kiddo's to play? :lol:
Have a 1t upgrade for t6 that gives 50k atk/50k Def or the alternative in spy. Purely to drain money out the game but give extra stats that won't destroy the game. You either spend a crap ton upgrading for a permanent stat increase or keep it In allies and risk losing it
