So i lvled 1-70 as disc, now i've been hearing a lot of great things about lvling as shadow esp. since i mostly do quests and not dungeon heal, so i respecked shadow and now a little bit confused. The main problem is that i do not kill mob before he gets to me and if i manage to pull 3+ mobs it's a problem allready, putting on all the dots + debuffs leaves me with less then 30% mana and my dots alone ushually don't kill, so i have to use shadow fiend + disperse. From the disc side lvling was fairly simple for both, single mob (bubble,holy fire, penance,smite,mind blash,holy fire) and from aoe pack farming (bubble, reneve,holy nova spam). I never tried holy lvling but i think it's close to disc. So my question is : what in your opinion is the best leveling spec and why ?
