You don't need 1200+ accuracy to hit ircinraq. No one joined your group because it seemed like a troll shout, kind of like the ones you've been doing about free experience points for 2 million gil. If you really want to defeat ircinraq you need to bring a brd and a geo for madrigal, precision, and torpor. You don't need to shout for someone who has 1200 acc on their gear alone.
