end game idea : Rebirth for a skill tree: in this skill tree you could level passive without any max level witch give more max level on skill witch have max level (for exemple gem waster ++ witch give both gem waster (andGW+) one more maximum level)
unlock after the gem and give 1 skill point evry 10^x gem on you.
Could we PLEASE have the base damage / speed of our stuff cause multiply by X is cool and all but if you don't know what's you base speed nor you base damage it become quite tilting to see "100% more base damage" dealing nothing (like 0.001% increase may be)....
PLEASE could we have a suicide button , on unkillable build (tank thorn with A SHIT TON OF VITALITY) you actually can't reset for a LONG LONG LONG TIME even if you want.
to the Dev, if the speed X8/X16 is a problem why not change it in "Unlock 10/20/30/40/50/60/70.... tier of Wave Compress". making a use for Green cube at hight level and reduce the lag (I think)
3 bad point tough :
1) Can't Dismiss / class the owned pet.
2) Can't start the next attack sooner (At the end it's getting boring to wait attack from ennmy)
3) The Shield who make you special Hit YOU'RE TEAM .... God dayum annoying.
