I remember i quested a undead Warrior with Kickz Profiles from 80-85 without any trouble. I used Dunatanks Warri CC- This was in Cata. ^^
anyone who has problems in hyjul with the stuff you gained from 70-80 doesn't know how to run a bot. because I have leveled 50+ characters 1-90 and never had an issue of dying only an issue of stucks.
With SOR's; Mount Hyjal[GRIND] 79-83[SKINNING] (untill lvl 81-82) good uldam 82-85 (till lvl 85) ussualy takes me about 10 hours, since i mainly use Hunters/Druids.. I spec BM, and get a MOP 425 ilvl (if i remember correctly) bow.. and run it with Singular, since the bow basically 2 shots everything with arcane shot On my Druids, i ussualy just do the same, get a good staff or polearm, spec them feral - and the instant free cast Heal of touch (to full hp, since feral is OP) keeps it alive.. both classes i find superb for grinding, since they do a ton of dmg.. and can cleave most things down (even if the mob area is 3+ lvls higher than the char) for my 1-90 chars, i ussualy use Kicks quest profile/s. The CC is diffrent from class to class, but the best way to do 1-90 imo. is deffo. questing, but the 80-85 questing profiles seem to get stuck or simply bug out all the time (in my case!) so grinding is more.. of a stable flow of EXP.
84-85 is hell for me in uldum...i am doing it on 3 chars at the moment. every half an hour they are stuck...
why worry about 80-85 being afk, on every realm theres at least someone who boosts you to 85 for a few k per lvl. You get 80-85 in 3-4 hours while being afk. 80-85 cost me 5 k since i was allr halfway into lvl 81. Took 3 hours and i was afk the whole time. Search for these boosters, its botters as well, but who cares. I know a lot of people who do 80-85 this way. Prolly raf ones doing icecrown farming, but who cares.
