As a tank, I have never minded explaining fights to anyone. The only exception is AK because I know the community attitude towards it and I'm afraid if I ask if someone is new and someone says yes, the group will instantly disband.

Yeah, no. If you wanna go into Garuda, or Titan, research that. Ifrit, research it (he's not remotely hard, but you can't know if something is hard til you look it up) but honestly, a four man is a four man is a four man. If you want to research it, that's great great great, but I'm not making you.
