With the implementation of Thunderforged gear there are now 5 different levels of gear that can drop from raids and lfr.
I personally think there are enough item modifications already that this is overkill. There are gems, enchants, reforging, and adding 8 item lvl to items already. And every time you receive one upgrade 3 other items have to be re-gemmed, re-enchanted, etc to optimize the gear. This is especially weird after they just announced removing the npc's in 5.2 that added the 8 item levels through valor in 5.2. IMO, not a big fan of this right now.
What do you guys think?
