It was exclusive because of procs and SE did it on purpose. Its too convenient that it only takes 2 jobs to cover blue and red each, and yellow took 3 one of which happened to be the only healer. Don't blame the playerbase for trying to do things efficiently and intelligently. Not everyone likes to come along as dead weight. Not that many people like to invite dead weight either.
You're making my argument for me. It's your call who you bring or don't bring. You're the one making others out to be "dead weight" when SE even created a way for any melee or mage to contribute even if they aren't fighting the NM! Get a couple extra people and they can feed you time and pop items so you can pop ad infinitium. They can earn you extra curor (aka gil) and XP WHILE you're fighting NMs. Maybe those things have no value to you, but compared to past events that's downright revolutionary. They never let you kill 2 birds with one stone before. Maybe killing trash mobs isn't glorious enough for you, but don't say it's not helpful in Abyssea.
What SE did was open up the game, but many of the supposedly brilliant minds in the supposedly friendly community took it the wrong way. Rather than decide that they can get everyone in the LS geared up to epic proportions in relatively short order by working together, our glorious leaders had the same idea as you. "If I don't NEED you then you're dead weight. Me, my 'girl'friend, and my BFF can kill everything ourselves! The rest of you guys are on your own!" There was no reason to do this other than selfishness, inability to adjust from old event mentalities, or some OCD thing about efficiency. That's not an SE problem, that's a player problem.
If my LS-mates and other friends want to come along for seals or items they're always welcome whether they have one of the chosen jobs or not. If you don't feel the same way then I dare say you're the one who's doing it wrong. Said it before and I'll say it again. Why play an MMO if you want to be exclusionary and anti-social?
