SPvP goes on a whole different trait build that is saved separately from the PvE and WvW build. I think there should be seperation in the builds also between PvE and WvW.
Note: This is not suggestion for double or tripple builds that can be swtiched at all times in wvw or pve.
I suggest that because the 3 parts of the game are entirely different – the SPvP has reduced stats, the WvW has all stats, but its almost pure PvP and the PvE is… well not PvP. Going on WvW with a build that’s is optimised for killing stuff and not defending with it isn’t the best idea, nor going on with defensive build(used in WvW) as ranged attacker at PvE. Currently its really cheap to reset builds but, its “kinda”(a lot) frustrating to constantly reset traits and replace them in the other build. The problem is actually the replacing.
