The devs completely ruined this game. It used to be good. The made it lag horribly, while continuing to make balance worse by buffing OP heroes (all father) they everyone already plays.
This new energy system is much worse than before. I now have an infinite amount of energy and no way at all to spend it, because I have finished the part of campaign that is unlocked, and there is no on left to pvp and no other way to spend energy.
Those of us who are higher level need more bots to siege, because we cannot continue adventure mode due to level 10 required. Once you beat the few high level bots that are in the game in pvp mode, you cannot attack them again for 24 hours, but you have extra energy. This is pretty funny because when you start out you cannot get enough energy to get going.
Perhaps the pvp bots should be attackable more often, like every 6 hours instead of 24?
To everyone complaining about micropurchase/pay to win: You dont need to spend any money at all on this game and you can get a big collection. All you have to do is replay the campaign over and over. (So you can complain that its grindy if you want, but its not pay to win). I currently have 3rd highest collection score, and Captain_Catface has #1, and either of us has spent anything, we are just playing through the campaign mode.
