As the title says.
Mostly because when you go to PvP you tend to slot different stuff; like several PvP potions, siege weapons, siege repair, forward camps, different emoticons, etc.
It woud be great if we don't have to constantly re-slot stuff every time we change from PvE to PvP (something that I curently do many times daily).
When you are in PvE zone, PvE quicklots wheel would load, when you are in Cyro, IC or BG, PvP wheel would load (unless you want PvE wheel to always load regardless zone - you may select this way from game settings).
Thanks in advance.
