[b]Ok this is a new thread ,PVP gear vs PVE, I was wondering does pvp gear work in pve environment and is it better to pvp gear out as your trying to get more ops gear?

Until you get to hard and nightmare ops gear is pretty irrelevant.

But the pvp stuff is better than the stuff you get from dailies.

PvP gear has inferior endurance and main stats than the PvE equivalents, but has expertise. Since expertise only helps in combat with other players, PvP gear is therefore inherently inferior for PvE gameplay. However, I have found that Champion gear is certainly viable for normal Ops, and perhaps even HM flashpoints. Beyond that PvE gear is pretty much a requirement though.

On the same tier PvE tends to be better than PvP. But tier 2 PvP gear can be better than tier 1 PvE (and 3 PvP better than 2 PvE)

Tier 1:
PvP - Centurion
PvE - Tioneese

Teir 2:
PvP - Champion
PvE - Columi

Tier 3:
PvP - Battlemaster
PvE - Rakata

As said above for HM Ops you want Columi gear at least (1650 main stat buffed, not sure about Endurance for tanks but HP should be over 20K)

NOTE: After 1.2 the names and tiers are changing, for instance Champion and Centurion gear is no longer attainable (even though you keep it if you already have it).
