I'm going to guess that most folks will say their ranged weapon is top priority. I currently still lack an epic ranged weapon so I'm leaning right now towards trinkets and/or tier armor.
I'm having trouble justifying spending valor on LFR gear at all (barring maybe the gun from Terrace due to the sha socket). So I'm really curious as to what other people are pondering in the way of Dos and Don'ts for the upcoming upgrade system.
The way things stand I think I'll probably just dump points into Relic of Xuen, normal tier, and maybe Windwalker Spaulders.
