Need help deciding a secondary.

I need help deciding a secondary, and probably a build for it. Primary must be fire. Secondary cannot be Regen or Willpower. Here's more details:

- Need to be able to solo to 50 at a reasonable pace, not a powerhouse, but doesn't die often.

- Works well in teams.

- Works well with a Magic/Witch origin.

- Doesn't look dorky.

I think the best might be Fire/Dark. Dark Armor benefits from crowds (Dark Regeneration, Death Shroud) and benefits teams (Cloak of Fear, Oppressive Gloom). But it will also solo OK. You'll need to learn to time Dark Regeneration, but I find it much easier than timing Regen's clicks. One problem will be endurance. Fire can do a lot of damage, so burns through a lot of endurance. Dark Armor can also burn a lot of endurance. You're going to have to pull out all the stops on endurance management. As long as that doesn't sound too daunting, I think it would work fine. Someone with actual experience with the combo could probably give you better information, though.

I think Invulerability might be a good choice as well. I think it looks dorky by default, but I'm guessing that power customization will take care of that problem (I haven't customized my Invulns yet). It benefits from large crowds, and I'm guessing would be more survivable or at least more straightforward than Dark Armor.

And of course you could always go with Fire Armor and just be a fire witch.
