I usually only pull large crowds when my healer is comfortable with it and my dps can handle aoe. Other than that, I try to keep things small-medium if possible. I ran snowcloak the other day and the healer wanted me to pull large crowds. I didn't want to since we didnt have a BLM or Bard, but since he insisted for several mins., I did. Healer couldn't keep up the heals, and we wiped. At least he finally stayed quiet afterwards...
