Thanks for the info.
Just to clarify when you say story mode bosses at 90 eng, not 100% sure which you are referencing? Like the new area open since I quit or special events ? Is it repeatable by the sounds of your comment? I’d like to grind some Gia else where and safe my moog grinding for the pyres.
As far as tanks so typically 2 tanks 2 chainers and healer in general cases?
If that’s the case I guess I should t be wasting time getting Rams enhancement and just focus on my two tidus
They are special events, but repeatable. The "final area" of these events is 4 or 5 missions, and they cost 90 nrg to do, and drop crysts, the final boss has a decently high chance of dropping one of 4 cryst types (There are 2 90 nrg areas, one drops power, support, tech and I forget what other, the other drops healing and all the rest.) Typically I farm that when it comes around since you don't have to spend lapis to unlock, and each run will get you some of every cryst type (Though chamber is better for smaller crysts). I'm sure they were probably around when you were playing, I just worded it poorly. But I typically farm hard in them because they are, I think, the best source of crystals if you can do them while carrying 2 xons and a cape.
However, story events usually only come once a month or so, they typically alternate story/raid/mog, at least since I've been playing.
As for the group set up. I think the standard now is 1 tank of the correct type. An AE magic heavy fight, bring a magic cover tank, an AE physical heavy fight, bring a physical cover tank. A single target heavy damage fight, bring a provoke tank (Or honestly cover tanks with golem+Moogle plushie work really well). Warrior of Light and Mystae work more than fine, but Basch/Willhelm are considered the top tier (However, the difference is small, all the tanks are really good, WoL is amazing, as is Myst).
So 1 tank, 1 support, 1 healer, and 2 chainers from what I understand. That can be augmented though, like the current esper trials a lot of people are using 2 tanks, a provoke and a magic cover. And in some cases, supports can heal enough that you want 1 tank, 1 support, 2 chainers and one finisher for extra damage. And I saw you had Olivia...Olivia is a great finisher. The Wiki changed their ratings and all "finisher" units got downgraded because they are being judged by their solo DPS and utility compared to chainers full chaining, and the reasoning by the Wiki admin was that very difficult content is better done with a support instead of a finisher (Because very few of them have DPS constraints?) and thus finishers had to compete for slots that would otherwise go to chainers. But don't let that fool you, Olivia does ridiculous damage still if you can fit her in as a finisher, it's just that often times finishers get dropped from what I understand. But, then again, a lot of different strategies outside the "norm" work.
