I think the biggest issue is not necessarily that there's nothing to do, which I do agree on, it's the fact that come 2.1, Crystal Tower is going to be EASIER than Bahamut's Coil. I don't understand that at all. If Yoshi was smarter, he'd see that a good majority of players are PUGing their way to Turn 5. Hell, I joined a PUG group that turned into static and we got to turn4 phase6 in 2 days. Not saying that's amazing but your "end game" dungeon shouldn't be doable by a handful of random players getting together and instantly become cohesive enough to get through it.

Tower should be harder than Coil. Makes sense that the 24-man would be HARDER but maybe I'm crazy.
