I just got my first Boxing team to 80 and they are DK's. I cant speak to a comparison of before and after, but I can tell you that They are pretty good at what they do. I quad box so not quite a 5 man team, but close. Havent tried any kind of instancing yet. Without a dedicated healer I'm not planning on it going well. I am currently working on my Paladin team. Got them to 58 last night so Divine Storm, here I come! I will say that nothing can defend a capped Graveyard or workshop like Army of the Dead x4. Except of coarse for AotD x5. muahaha. I have found that in my extremely bad gear I can take 7 or 8 Horde on at once with my legion without losing all of my team. 9 Horde seem to be my breaking point tho. Hope this helps. Just remember, Im a 'boxing newb so take it for what its worth. I enjoy them alot.
Feel free to pst on Anetheron, Alliance side. Pestilencê, Faminê, Dêâth, and Wâr. (I couldn't help myself)
