what if we had upgrades that could be bought with evo's? lets say... increase dretch speed or increase secondary attack strength. something that we could buy with evo's that could last the entire game. but would take like 1 - 2 minutes to upgrade. maybe... 9 evo's from the team to get a dretch speed upgrade?
i think that if there were an upgrade system it'd be best to have it on an individual basis (since not everyone specializes in the same classes) with a small upgrade time (30 seconds?) that requires evos to be stockpiled and used all at the same time (to make you REALLY want to go goon, but also make you want to save up those evos for the 15% health upgrade). in NS they've got a gestation period where you're immobile while you upgrade ("you gaiz stole frum ns").
