I assumed that much, still we will have to wait and fully see the impact of its removal. As we already know now, PvP is now wager on two aspects. Stats and player skill. It is the stats aspect that has me curious and what it is we will expect in the coming months. I've already spoken with several writers of numerous PvP guides and many can agree we will see builds harboring towards min/maxing and stat layouts based around skills used. It's certainly looking to be a more diverse system than it once was.
Actualy the removal of expertise should make world based pvp significantly more balanced. Because of the level scaling, one of the issues currently with world PVP is that expertise does not scale down. Without expertise all stats should normalize fairly close to each other with the level scaling.
