It can be done. Its not a great thing. Not very strong at all. Tanks should stick to tank farmin'. I know because I made my warrior into a 55'r. I used glads defense and things like cyclone axe. I'm sure it might have been a ton better if AOE hadn't been nerfed... !>.<!
i tried it as well, was ok just had some nrg managment problems, and tbh u can farm anything with a warroir without going 55 only area that it was used for is UW but there is already a guide to do that without 55
