I did my relics for bard, smn, sch, and blm up to Zenith. I was intending to go farther but then I saw all of the ridiculous hoops you have to go through... I'm sorry but I play a game to have fun. Not to endure it.

Dungeons = fun
Coil = fun
CT = fun when you're not surrounded by idiots. (did a server only run...smooth as butter and everyone joking and laughing.)

10,000 Fates = not fun (yes I know, I'm exaggerating a bit...or am I. there are those who can't get out of atma for lack of luck)
God knows how many Myth to buy books that give you a long list of monsters, dungeons, and yes...more fates to do.
millions upon millions gil worth of materia to finally make the perfect weapon...that lasts 1 and a half month before the new tier drops.

I'm having more fun spiritbinding materia to overcharge those gluttons for punishment. I hope the next advancement for Relic involves materia too. I'd like to get a nice medium personal house. I have one scouted out...that is if they use the same housing ward design.

At least with CT/dungeons/Coil, I have a chance of coming out of the run with something even if it's just Soldiery tomes. All of the above...you do that for one item. The work does not equal the reward.
