Looking at heroic logs from other Vengeance DH, I was curious how they were getting Symbiote Strike to account for such a high percentage of their DPS. Turns out, friendly fire triggers Symbiote Strike, and so these tanks can just drop their debuff on the raid for a massive meters exploit. I’m pretty sure this damage only applies to teammates and not to the boss, so it’s purely meter cheese and shouldn’t be counted on warcraftlogs rankings.
