Just as the title says. Pretty much from 25-50 all I did was PVP and do instances so when I got to level 50 I basically had nothing but favor with some blues from instances. Now I'm trying to get some essences and get my physical crit as high as possible and I'm realizing that everything (at least from what I'm seeing) requires rift items, expert dungeon items, raid items, etc.
So are there any essences out there that a purely PVP rogue can get? It's fun to PVP... It's not fun to grind rifts all day, and right now I don't have the time to do expert dungeons and much less raids.
