10man is crazy ez with 5mages, i've went in and nuked sarth without clearing the trash b4 (sometimes die after sarth does) on 25man it's doable as long as i have one tankish person with me to keep sarth off of me for the first 30seconds, he goes down pretty quick, granted 10 is a lot easier and easily done with just my 5mages, the money you get for doing 25 makes it worth the 10minutes it takes. haven't tried maly 25 solo (not really solo, but u guys know what i mean) me and pretz (a 10box guildy) he took a 5man team (paly 4dk) and my 5mages, we nearly killed maly in phase 1 in 10man, id say 25 would be doable too with little help, but well worth the trouble for the loots (disenchants and gold) and the mounts. for some reason tho, i have noticed that ony is quite a bit tougher, my dps is a lot lower on ony for some reason, i don't know why though, maybe he has some arcane resist or something.
