Once when I was lvl 39 or 40 just for shts and giggles, I decided to see if Redwind would still aggro on me. I knew he didnt drop anything that was useful to me, but him and the Lich are about the only things that I havent killed or helped to kill in my home zone of Everfrost (and I mean monsters by that, hehe). So I mosied up the ramp of the ruined temple and Redwind immediately aggrod on me, and brought his whole horde of icy orcs with him. I fell back and began to root my heart out, but Redind was close enough that he fired off his HT and it hit me (which surprised the crap outta me). My pet was already goin nuts tearin the orcs, but shaman pets are laughable at best and he didnt last too long. At my lvl my pet was prbly about the same lvl as the icy orcs, so lets do the math 4 warriors + one SK and his pet vs. one shaman's pet. I would put my money on the orcs, especially since I had decided to see what was goin on in Permafrost about that time, lol.
I've gotten a little bit more powerful since then, maybe I'll go back and see what Redwind is up to, and introduce him to my new line of pet spells. ;)
