Maybe by not doing it falsely thinking you are forced to do it, like i didn't start to do some pvp even though i think that having some Garo's stuff in dyable version would be cool ? I know quite some 70 players who dont care about being max rank in their GC, and if asked wouldn't even know how to do it.

If optionnal content piss you off then just don't do it, otherwise you will only end up having a bad opinion of the game. A good example of that would be the yokai event where numerous people forced themselves to do in a few days hundreds of fates they dont like at all, and ended having a burn out and canceling their subscription. Meanwhile, not disliking fates and by doing it a little from time to time i have only 2 weapons and a half left, and i hardly see what is so hard about this event if you know what you are doing.

That being said i am sure looking for bringing my squad in dungeons, hoping that the limited number of them available (5 at first) for that is gonna meant a better AI than the chocobo staying in every aoes.
