Minions or pets are fine in the Saurfang fight.
This includes our minions, mage pets, hunter pets, and any other pets.
They are not affected by the blood at all.
My logs have not shown them taking blood damage. I have yet to find a combat log online that indicates a minion (no your fellow raiders as minions do not count) can be affected by the blood boil. If you have a link please share it with us… otherwise…
Any reports that minions cannot be used are greatly exaggerated.
