Seriously cannot believe what im reading here, OP how much have you learned in all those hours of PvP?
im a returning player crossing back from ESO PvP to WVW in here as a Ranger.
With less than 100 hours or so in GW2 wvw even i have no problems with Reapers (Scourges on the other hand!).
LB/GS, Lightening reflexes, muddy terrain and use the Jacaranda because if owt needs a nerf its that bloody plant.
Honestly if shroud is an issue keep at distance and wait until its over - then toast um.
Even better just swap to a Druid, root root root, they never get close.
