yeah ask anyone priests are definitely one of the hardest classes to level up. I have one myself (see any resemblance in avvie?) and it was a pain in the butt to level up lol, I just started running instances non stop at one point, but that was before they buffed getting XP like crazy.... anyways I use dot dot fear mind flay mind blast on multiple mobs, or dot mind blast wand on one mob
I always opened with Mind Blast or the touch that requires a cast time (can't remember which it is, the mana or the health one, as I haven't played my priest in like a year) because then you have more time to hit them with other stuff while theyre running at you. If you hit them with a dot first, then start casting Mind Blast, by the time you've cast it the mob is at your feet.
