From what I have tested in WvW, the new Blast Gyro does not seem to grant the superspeed from the Shocking Speed trait.
That is all.
Can confirm it. Tested in PvP and PvE
Can confirm it, too.
The tooltip shows 5s Superspeed, but it neither happens at start nor at the end of the animation.
Allies also do not get superspeed from shocking speed.
If kinetic stabilizer is traited, the knockback will grant superspeed.
Since superspeed duration does not stack, I'm not sure which superspeed duration will come out at the end (probably the 3s of kinetic stabilizer).
Would be really nice as an offensive support option in WvW, if this would work! ^^
