If you are going to do this you need to not allow current PvE T4 gear into "pug" minis.
At current T4 is the best gear defensively and offencively against melee characters.
It does, however, not help against T4 gear magic casters FOR the melee characters!.
All the minis at the moment are flooded in T4 casters and rangers and not allowing us T4 pvp in pug is completely absurd.
If you go this route you are completely undoing everything from when you added protection to pvp tiered gears. Which quite frankly is a step backward for half pvp players (Melee/non caster) and straight up advantage for casters in pug games.
