I have 3 accounts. Each one has a favorite brute, tank, and sentinel. They all have different power sets. My main account has a warshade and spider that are both so decked out I see no reason to start another. I’m still working on other classes. If I had to pick just one to keep, it would be my electric/bio tank. Thanks to adaption it can be a decent damage dealer or it can be a great tank with several powers to keep it alive. I can easily run it solo at +4*8. At least as long as archvilians aren’t involved. And maybe even then.
