Sort of. He has multiple clips going into detail explaining what to do in a bad situation and what a mage's responsibility is, so he knows what's suppose to happen. Shit hits the fan and he can salvage the entire situation by doing the most basic job of a mage, casting rank 1 Blizzard. Even if he didn't have 2 extra sources of mana, he could cast rank 1 blizzard multiple times because of how cheap it was. Some argue he was even intentionally burning mana to maintain the lie "I don't have mana, I can't help!"
People aren't shitting on him because he roached out and ran. People are shitting on him because he blatantly roached out, claims he wasn't being a roach, and continued to pretend to be superior to everyone in the room while displaying himself as a giga retard. He then doubled down by banning words like "mana gem" and then tripled down by claiming it was too risky for him to do anything when he wasn't in any danger. Now he has quadrupled down by writing up a tweet pretending he's a victim and content creators making fun of him are burning bridges when everyone is in agreement that he's being a clown.
It's less to do with the game and more with his turbo faggotry that revealed itself during the game. This is peak lolcow behavior.
