Locked out of future MSQ progression?

[BillyKaplan]

Because it just winds up like the "escape game" in O3. It's nowhere near as fun they think when you need to do it more than once, and they aren't going to make any mechanics based on you quickly determining the flow of random tiles on a field, because it's too hard to do during a fight instead of an intermission.

If you want to talk fun vs. ability, the latter being the leading argument throughout the thread, then it's highly subjective and I'd hate to see that sort of thing go away. Similarly, I adored both that mini game as well as the trial in question in the MSQ.
Also, when it comes to MSQ, which is again, what this thread is about, unless you run alts you never have to bother with it again. And even if you run it on alts, that's a very limited amount of times you have to run it, opposite to content that was made to be farmed like Omega.

Or, in this case apparently, "Deflect any orbs before they touch an ally!" or some such.

That's exactly what you need to do, with a duty-specific command showing up, like in Lakshmi HM
