I think everyone should be able to loot the chests. And, if there are any things in need of the skills (Thievery, Religious , Etc. ) should also be allowed to be given to every character in the dungeon.
I chose a wood elf for my rogue ... since they get 10% resistance to effects that slow their movement and they get an extra 1% added to critical strike. I am building my rogue for PvP.
