I don't want to sound rude. but I think that the drop rate for the lvl 60 items in the Waterworks is unreasonable. I have done the dungeon 3 times. I have spent over ten hours total in the waterworks. I can't seem to get either my school's hat or robe. I have also gotten my school's shoes 3 times. If your not going to increase the drop rate of the school items, could you at least make it so that you can't get the same item twice. . Making it so that you can't get the same item twice will increase the chance of getting the item that you need.
I stopped counting my waterworks runs after my 50th time through and I am still missing equipment, but it does drop. All my wizards I have sent through the waterworks are complete, with the exception of my Life mage, whose robe still refuses to drop. I’ve gotten the life mastery and balance mastery amulet drops, but still no Life wizard robe. Aaaarg.
Just need to keep doing runs. The mega snacks alone are worth the trip.
It took me 4 tries to get all of my legendary gear as well as a mastery amulet. The trick to getting equipment is attacking as much as possible and not dying. This works best on the last duel with only you and another wizard. So both of you can attack a lot.
Good luck in the Water Works Diana Dragonpyre Life: Legendary
