You haven't played this game much have you? My healing style? Yeah ok. I don't acquire any hate. Dude is getting low on health. I cast a single Sacrifice 1. Mobs turns on me. I don't cast anymore spells so that he can get hate and since he is now at over 80% health, I figured he would. He didn't. I die. Same thing the next 2 times then I ask him to voke. He does. It works. Next mob, I ask him to voke. HE SAYS NO! Because he didn't want to take damage. He didn't even know what a tank does. If you're going to play a MMO, you should AT LEAST know the basic roles of each playstyle (Tank, healer, dps, etc) and he clearly knew what a tank was, but HE didn't want to be the tank....as a GLA...So say what you will, but people like that, even after being asked to tank correctly and being told which skill will allow that, have no place in parties and I'm glad he can solo because I'm never inviting him to a party as anything other than DPS ever again. I hope he can solo Ifrit too because even the Arc, that was from his LS, got annoyed with his bs.
Learn your classes, or at least know the roles of each class, or hope that SE lowers the difficulty on raid mobs...because you'll never fight them more than once at your pace, kiddies.
