My Stone/SS tank had some problems after ED, it was not the same. However; with a little bit of math I was able to fix his problems. Invuls got hit hard unfortunately (glad I never had one). My Rad/Elec defender got better after ED, he was finally able to dual Dark/... Defenders in the area. ED I think diversified the game more, and made people have to actually think about how they wanted to slot their characters. Was I stronger pre-ED? No doubt (Remember Regens tanking Hami solo like?), but did I become a better player after ED? Hell ya, how else would I survive the devastation. At times, the game got a bit scarier after ED. Hahaha!
