I really like the game. However, once you reach level 20 there isn't much left to do. Missions take 3 hours, I can't build anything and there isn't much to do with other players - besides help them build or steal stuff I don't need anymore. I'd like to see some new building (maybe have a class requirement like a clinic for the medic) . Mainly need some sort of coop with other players against herc troops or something and some sort of faction system.
It would be nice if players could get a bonus for inflicting 0.1% damage to a world boss instead of 1% - or just give the bonus to the top 100 players as that might scale better as people level up. So far I've only seen the top three people even get to 1% and they get other bonuses.
There was a problem. The specified queue is full.... then how did I click to build something? It's annoying that you sometimes need to wait 5-10 seconds after something is built/upgraded to build/upgrade again - it's really annoying when just starting.
