I just reached 100 on my Warlock the other day and did some grinding for gear. I'm happily 655. However, I don't do that much damage.. I do at most 25,000 in 5 mans and maybe around 30,000 fully raid buffed when I did Kazz. But solo I'm only doing maybe 20,000.
I feel like that is pretty low considering my Frost mage at 640 item level can burst up to 50,000 if I get lucky with crits. So is Affliction just overall bad at low item levels this expansion? I tried the other Warlock specs but I didn't really enjoy them as much as I do Affliction.
