If you think it's cluttered now, just wait until we get to the size of the dmm version's plat recruit. There's a good 100ish different units in it.
Makes me sad too because I've been playing since day 1 and as a F2P player, I know there will be many, many units I'll just not get. I'm still looking just to get any Acht unit after a good 30+ plat draws since she was moved to it, and a few exclusive draws when she was in there.
