SoD Onyxia is severely overtuned

You’re a green parser telling people they’re bad. You can’t make this sh!$ up.

Onyxia requires each and every person to watch their threat and position

No it doesn’t. You just need a tank with threatmeter to tell people when to chill on threat. That’s the whole fight. Onyxia isn’t hard, but she is overtuned in that she has way too much HP.
