Can't make a full premade for Crystal Tower...

I think that in a week's time tops CT will be puggable with your eyes closed.
It is ridiculously easy, you can have people dying, disconnecting and calling names instead of explaining the first timers what to do, but at the end of the day, once you know every mechanic, there's so much room for error that it's not even funny. Took me over an hour in a completely random DF group where barely anyone had any experience to clear it for the first time, making every mistake possible. The next run (also DF) was done in a flash and felt like a steamroller, because it was a 2nd-3rd run in a row for all groups and people knew what to do and what to avoid. If several premade groups with coil/myth gear meet, they'll probably speedrun it, and a complete, 24-man coordinated raid will turn it into a snooze fest with flashy lights.

I can already see leavers, trolls and griefers (think intentional leeroy/screwing up on purpose) will be a bigger problem than the bosses.

I hate to say it, but it's already started. A little while ago I got out of a CT where I'm pretty sure one entire group was nothing but trolls/griefers. The other group was a bunch of douchebags (refused to enter the first boss room until we agreed to tank him in the center, kept yelling at people for "doing it wrong" even when there were no problems) but at least they weren't trolls or griefers.
