However the most viable solution to PVP problems is the removal of Expertise / PVP only gear. 2.0 would be a perfect patch to remove expertise.
That would require the high end PvP gear to be on a par with the high end PvE gear. PvPers would be able to entirely skip the intended PvE gear progression and just jump into the hardest available content right away and Bioware, obviously, doesn't want that - I'm almost sure that is part of the reason why the BiS PvE gear is of a much higher item level than the "new" PvP gear in 2.0. The far lower armour rating, min/max damage and Force Power/Tech Power on the PvP gear will make PvPers gimped in PvE content; Expertise gimps PvE gear in PvP content.
