Necklace is min lvl 18 right? Ill farm one when im 17 prolly. The xp starts stacking up a lot so shouldnt be that much of an issue. I have Icy burst, shocking burst of 5% to play with for a bit. Ill try to find a better set, but not going to spend a ton on em.
The UI thing wont be a huge issue, and I am expecting it for sure. As far as playing the level 20, I will prolly play a little to let my other planned reincarnate round out raid timers and get some more gear/tomes. Then I can reincarnate them again together
