I mean, if you can't beat him, what hope do you have to run Coil? If the problem is your skill, well, your skill will be the same on Coil, so you're getting stuck again on the next endgame progression dungeon.
it could be the partys not the person remember that, garuda for instance first time there i was one of the only people not to die yet everyone else did, 4 partys of useless healers and tanks later finally got a run complete, so consider who people are going with not the persons skill

also look at ifrit HM easy fight if youve seen it before and know the patterns but you still get the useless people again its not always the persons skill its the party they go with
