I'll try to be short.
I play a Invul/SS tank, and the way I've respecd my character, I am basically a Provoke machine. I use taunt and provoke like my main attacks. I also have Punch, Haymaker, and knockout blow as my main 3 damage attacks.
I rarely go crazy with attacking in a fight, because I'm more focused on keeping things on me, and off my team mates. Uping HP on mobs didnt seem to big a deal for my toon, because I'm not a damage dealer anyway, but then I asked...can I solo?
I can hold mad agro, like +3-4 minions and Lieus, and a boss here and there quite well without really needing many inspirations. But, as is, it takes me several minutes of cycling my attacks on a -2-3 boss (or lieus even). So I'm basically usless as a soloer unless I respec more damage bubbles into my attacks, and reduce my damage sponge abilities...
Any commments from some other tanks with this problem?
Or am I off my meds again

?
