In my opinion Pve trinkets should be disabled in instanced PvP, but i also understand that many people like the variety which Pve trinkets brings, so if they are not disabled in my opinion they should NOT be your best dmg source.
In this video you can see pikaboo using the SKulking Predator (14:07) trinket which did more damage even from the rogue Kyrian ability and its his TOP dmg (8k dmg in single hit). In my opinion that is way to much dmg for a trinket and specially combined with already very strong burst of rogue.
Please consider either disabling PvE trinkets in instanced PvP or lowering their DMG to some acceptable levels.
I try to understand how this ist not the case atm. They had the exactly same issue with discs schism in bfa and fixed it after months. Why and how they can itroduce the same issue again.
Yeah its a mystery, I hope it gets removed asap because til we have best gear, its easily bis and a raid trinket being bis is just stupid and frustrating.
