Why don't you suggest a changeable cap in damage? because I think surges are supposed to be fast, for instance patches have td and the upper spam, and rams have a Long trans guages, which kinds make a combat triangle, surge being weak to ram(trans) and strong against patch(hiting before that upper) and ram weak to patch with its TD. There is also a set speed button and with the damage cap I think It would be ok to leave the t3 un-op as people worked hard for it (refering to people who said +5-7 elec shouldnt become op). as the only big difference would be Hit points/ life points.
This is just my opinion/sugestion, I havent pvped that much therefor you might disagee. Make shure you tell me as I am open for idears.
