You can no longer ilvl cheese to fish specifically for CT. Other than that, it's a simple answer: the goal of an Alliance roulette is to gain XP and get tomes. CT takes 15 minutes and Nier3 takes ~40-45 for a similar amount of XP. Even a lalafell born yesterday can see that one is a lot more efficient per time spent than the other.

"Have you heard about the new Mass Effect game that just came out? It's the most time efficient one yet!"

It's genuinely fascinating to me that someone would value time efficiency so much more than fun that they would intentionally cheese to get Crystal Tower.
