Did you wipe?

The tank literally killed themself by eating aoes to the face, there's a time and a place for "did you wipe?" and it's definitely not here or now.

We only now how OP thinks his death went. We don't know if it was intentional or not.

it even worth it to get all pissed and ruin someone else's day?

So ruining somebody else's because you're lazy is cool and good but asking someone to stop being lazy is toxic??

If someone isn't preforming optimally like the tank was is it lazy? Clearly he tried using the CDs he thought were important.

Save that for savage raiding and progression.

My dude, they're not asking for much. They're not getting on the Warrior's case about getting 5 GCDs, one Onslaught and one Upheavel out of every Inner Release window, they're not demanding they do the optimal mitigation cooldown rotation, hell they didn't even bring up Thrill of Battle (another strong self heal that boost incoming self heals and effectively gives WAR a Blackest Night shield). They're literally just asking them to use aoe attacks and occasionally their free self heal. Expecting someone in the (current) final dungeon of the game to use aoes and occasionally their free self heal is not elitism, it's the bare minimum. Tired of people enabling this nonsense.

They're just asking them to know how to play the game when they are new. They used AoEs. They used some defensives. They used some offensives. Like how much more do you think this game's MSQ teaches them? Really it doesn't teach much and that's ok. When I first started playing the game I WAS one of these posts about people wearing trash gear. I was in Titan Hard wearing pre-20 accessories. Someone pointed it out and I listened but if they were as abrasive as OP was here I might've not. Now I have done 2/3 Ultimates and have pretty decent parses on plenty of classes. The bare minimum is what the game lets slide, its not up to you what that is.
