There can be only one.
Brawl/? Brute.
I've done the WP version. I would toy with the idea of making one with Fire or Rad or Dark or? But the beauty of Brawling Humiliator being a Brawl/WP brute was that because Brawl was set on Auto, you basically 'set him and forget him.' As in you target the enemy, hit 'follow', and then sit back and wait. When that guy is done, target the next, follow, and wait. Repeat. Not a lot of management except the occasional firing off (after he got it) of Strength of Will, or the occasional inspiration. Maybe he'd get hit with a quick mezz that turned off Rise to the Challenge, so he'd have to have that put back on.
That's it. I then just chatted and watched to be sure he didn't get in trouble/didn't need moving to the next mob, 'cause Rage, y'know.
So yeah. Brawler is a must. Have to do it.

Past that I don't really know. The Dawn Sisters are a must. As is my Claws/WP scrapper. And the only blaster I liked, the Water/Ice one. Of course, it'd be a hoot to see if I could recreate the absolutely dependent Defender, the one that could not solo to save her ass, but would be the most helpful teammate evar. I'm not sure I'd use rad/ICE again. Probably pick something even worse for her offense, if possible, and something better for her team help stuff, if possible.
However, I do know my overall main is the SS/WP brute, so after I do BH again, he'd be next up for sure.
And then, after those (which were all 50s+).... Hm. I dunno.
Guess we'll find out. I hope.
