The Worst Iteration of Monk. What could be different?

[Carighan]

That introduces some additional problems with MNK as you need a ~1.94 GCD to match up your RoF windows ideally

This is a problem, not a reason to keep another problem in the game. They should not justify one bad design with another that gets marginally less bad because of the former.

You'd probably still be drifting anyway - just everyone at different rates depending on their SkS values. (One person's 2 minute coming up at like 1:50, another at 2:00, another at 1:55, etc)

Yes, elimination of easy alignment would be another benefit.
