Just curious how you guys are fairing on your grind to 85.
Post your class, spec, and level and how your grind is going. Do you feel like you're killing slower/faster than others? Taking more damage? Don't have enough self heals? How's your downtime? Etc.
My Demo Lock is currently 83, I found the higher I level, the harder the mobs became to kill because the mobs themselves get a hefty boost to hp/damage while all my stats (crit/haste/hit/mastery) goes down as my level goes up. It's still relatively easy though, I just let my Felguard do the tanking, down time is pretty much non-existent. I have no mana problems while soloing, don't even have to Lifetap (although I might start soon, spells getting expensive).
Have an 81 Arms Warrior too, again, down time non-existent because of my 20% VR heal. Don't kill as fast as Lock though, ranged is still better than melee. It's still easy kills with no down time, so it's pretty good.
