I have to admit, it's really annoying to put together a group for the weekly EX primal quest and have "experienced" players join that can't deal with the most simple of mechanics. I've been in a Titan EX with an i90 DRG that got hit by every single WotL. I've done Garuda EX with i90 OT's that can't pull a twin when they spawn. And I've done Ifrit EX with i90 white mages that insist upon standing in the center with the dps when they have searing wind, and not understanding why the group is mad at them when we wipe.
I don't have a problem with people that use the Turn 2 enrage strat. I use it myself. If you can clear coil, regardless of how you do it, then you deserve the gear. Period. The problem comes when myth gear is on par with allagan, but is basically handed out for free. This, mixed with FC's selling EX primal runs, creates a population of players who can't clear content legitimately, that claims it can by lying about it's achievements and showing off the gear they "bought."
Since SE implemented the average ilevel system, that's what players use as a gauge for player skill. This doesn't work, however, because of what I mentioned above. If SE is going to continue to hand out top-tier gear for free, then there needs to be a different system in place for filtering out skilled players from un-skilled players when using the party finder. There is absolutely no reason to die 30 times on Titan every week because full i90 players do less than 100 dps while being unable to dodge WotL.
