Tanked with a warrior during tbc, not raids thought only a few instance. Also tanked with a druid and played my DK to 80 semi tanking with a mixed group.

I would CERTAINLY not recomend you to take a prot warrior if your cant singel box him properly!

Paladins are so easy to tank with, all you realy need to keep up is holy shield for some migation.

A bad tanked warrior migates nearly no damage.. And you have to keep shield block up all the time its not on cd to get a proper migation, well thats the way it was in tbc. Warriors got tons of fancy tools and is much more fun to play then a prot paladin but for boxing it can get realy recomend it since the fights can be more then enough challenging with positioning and healing.
