Nice. I have little experience with rogue comp. I used warrior comp w/meatshield build for most of the game and that paid off well for me. I mainly ran 2-h build so I was the hammer while she was the anvil. But then I started running cleric and it complimented my 2-h build beautifully. Not to mention clerics work great against undead. AC isn't the greatest because I put most of her points into Int and Per to boost her mana pool. Currently, she's at 24 AC with 160 mana with her healing ability maxed out. I'd say give her a shot but you'll probably have to tweak your bloodthurster build to compensate for traps. I run a balanced build with 5 in Int so I do my own traps and get decent Xp. That helps for when I need to switch to warrior comp for high lvl bosses too, so I don't need to rely on which ever companion I'm running too heavily if the path is laden with traps.
