Finished /PLD -> 37. Love the Auto-Refresh, Flash, and especially Sentinel (for those pesky Converts-under-fire).
Well, I don't know if it's much of an accomplishment, as much as surprising myself, but I tanked 4 Campaign Orcs at once for the duration of a Campaign battle, until the DDhorde found me and slaughtered them all.
Also, later on I got killed by Poisonhand (not the accomplishment), and reraised only to get aggroed by 2 Dismemberment Grapplers, which I tanked weakened for the full 5 minutes, and then popped Convert, cured up, and proceeded to kill both of them.
In short, /PLD is everything I thought it'd be.
