Nothing positive I am afraid.I am a president of a club and I have basically decided only limited war for the following reasons:
1.Incentive is too small.Noone cares about yet another moronic in-game currency. Why did you reduce the reward from 3 plat keys, 30 sims and 3 gold coins for the first arena, makes no sense.
2.Repetitive, slow, buggy and lags
3.War actually wasn't that much fun anyway. Too many people spending real money or cheating to get ahead.
There are thousands of other beneficial things you could have included in the last update.
It's actually kind of insulting that you think flashy backgrounds, cheap powerups and the ability to buy war items is even worthy of being called an update.
Oh, and one other thing:why the hell did you turn wars off in the middle of COM?
Let's face it, all you care about is making money and there is no problem with that, it's just you got greedy and lost respect for the loyal players. I have actually spent real cash on this game, but no more.
