inv/tw question leveling

[ryokoryu]

So I went redside with it and figured I could boost lvls by running the S/L comic con map and get myself to about lvl 20 quickly but whenI went in I couldn't kill fast enough to keep insp's going.  I started this at lvl 6 and am giving up on this for the moment.  Is this just because of being a tanker or would I have the same issue on brutes as well?  I figured having the 50 s/l resist at level 6 would be close to the 55% fire resist I had with the /fire brute at the same point.  Just not sure re-rolling it as a brute would change enough, this will be a solo character.
