Hi,
I'm a returning player. I recently came across a bard swarming 30+ mobs in order to power level another player. I've seen bards charm kite before, and I've done this extensively as a druid in Loping Plains, but never more than about 10 at a time. Charming has its limits. The pet dies way too fast when you go over 10 mobs at a time.
How is this being done? Would you consider this to be an exploit?
