The ONLY way you can be doing numbers that low in a heroic when geared in the ilvl required for heroics is either:
You cheated the ilvl requirement with gear you are not wearing/doesn’t match your stats.
You are afk and not doing anything.
You are just not hitting buttons or you are not performing your role mechanically.
Those are behavior issues.
They designed the encounters. You are not listening.
You have always been required to perform in a group, this is how groups work. Groups are player led. If you are not performing, expect to find yourself getting kicked a lot. This is entirely a thing Blizzard has said. No the ilvl requirement isn’t the only requirement for heroics. They are 100% player led and managed. I am sorry you don’t have the capacity to understand this.
You’re clearly here to intentionally troll. I do hope the mods actually bother to moderate. Sadly they likely won’t, but you absolutely are violating the CoC.
