Is player-made armor (the lvl 49 stuff you get from your crafting vendor) considered PvP or PvE? (I.E. does it have an expertise stat?)
You can move mods from pvp gear into player made moddable armor so that it will have expertise. Basically only pvp armor has expertise (mods) to start with.
If you "max-craft" that armor (break down enough that you get it up to its purple version) how does it compare to the other end game vendor bought armors?
Generally crafted stuff is always considerably inferior to proper PVE endgame gear.
Do either the PvP or PvE armors outclass the other enough that you can use one in-place of the other? (E.G. Can you PvP in Black Hole, or do operations in War Hero armor?)
