So far I see only 2 patch notes that should affect Draconic Echo, namely:
Draconic Echo: This trait now grants 1.5 seconds of quickness to allies when the revenant uses a consume skill, in addition to its previous effects. NO INDICATION OF PVE/PVP/OR WVW SPLIT
Draconic Echo: Increased the quickness duration applied by this trait from 1.5 seconds to 2 seconds in PvE only. PVE SPLIT BUT QUICKNESS SHOULD STILL BE 1.5 SECONDS.
Yet in PvP/WvW we are only getting 3/4 seconds of quickness even indicated in the WIKI. I swear when the patch was active I was able to do 1.5 seconds of Quickness per Facet Pop to proc Draconic Echo. Was this ninja nerfed? Whether my past experience is wrong or not, THERE IS NO INDICATION OF A PVP/WVW SPLIT TO 3/4 SECONDS ON ANY PATCH NOTES.
Even checking the Trait History in the Wiki yields the same, THERE IS NO INDICATION OF A PVP/WVW SPLIT TO 3/4 SECONDS ON ANY PATCH NOTES.
