Dunno about you becoming elitist, I'd say more of your temper is shortening over time of dealing with idiots, now ifrit is easy, the only aoe that i generally got hit by for the first few times I did it would of been the full zone aoe apart from standing next to ifrit and that was because I was unsure of when it came up, garuda on the other hand is just a lil bit more harder to get used to and needs more explaining than ifrit, after a few times of doing garuda I dare say it should be something to get used to as well.

All I can say is if the party isn't bad but there's just the odd loose screw going off that happens to make you all die then just stick it out as that's what I do anyway, I like to think of my self as a perfectionist and when stupid deaths/wipes happen I just simply facepalm and try to carry on through it, just if you're working with a full group of total half wits that refuse to learn, listen and even type back to the party...then yeah by all means just leave.
