PvE and PvP rolls are the same. It’s honestly irrelevant since the reason you are raiding in the first place is for that item. You have to realize the reason we Raid is for gear and it doesn’t matter what content that gear is for. All that matters is that it’s BiS and the reason they are in there. So they should have equal opportunity to roll on it.
If a Dps build requires a Tank trinkets for BiS in their build. They 100% should roll on it. If a Dps requires a Healing trinkets as BiS… Like that Boomkin and Solace. They 100% should roll on it and get it “IF” they win.
The excuses why it shouldn’t go to the Prot are not acceptable. Period. It’s BiS for that build and they are doing to raid to get that item. So roll on it. They won, Congrats to the Prot Pal for getting BiS. As for that Dps better luck next time.
This is just another reason why WotLK is awesome.
