I realized the other day that they took the time to nerf Ranger stances in WvW which strikes me as particularly odd considering that stances would be ranger best tool for group support and ranger are nearly automatically kicked from any organized group because they don't bring any group support.
Bear Stance: Cooldown increased from 25 seconds in PvE to 30 seconds in WvW
Moa Stance: Boon duration bonus reduced from 66% in PvE to 20% in WvW
Griffon Stance: Might duration reduced from 8 seconds in PvE to 6 seconds in WvW
Did I miss a time where Ranger was the meta group support and they had to nerf it? As far as I can remember, Ranger have never been welcomed in organized squad because of their lack of group support so I can't understand that nerf.
And, it's not like if the trait to share the stance was really strong since it only grants 50% of the stance duration to party members.
