So.. exploit of game mechanics or clever trick? You be the judge.
Warrior has a macro that does /sit and then puts up spell reflect.
/sit makes it so that all spells on the sitter crit.
Spell reflect causes
allone spell to bounce back on their caster (seems this is “broken” when the warrior is sitting the spell reflect lasts for the full duration and reflects all spells).
So for the duration of spell reflect all spells against the warrior crit on their caster.
