MONK is to confusing / annoying of a class now

[Shurrikhan]

(why do we still have timers when we could just have stacks those days??)

Because a job that's thematically been about constant uptime shouldn't need to hop aboard the train for "let's have three times the duration needed to actually use the originally intended number of globals -- oh, and let's make sure SkS is even more terrible."

MNK is a crit addict job, which means getting too much speed means sacrificing crit

The only crit interactions are with weaponskills, which are on the GCD and are therefore just as affected by SkS as Crit. (More actually, as the rate of GCD decrease is greater than the rate of crit chance increase, iirc, since part of the value of Critical Hit goes instead to increasing the crit modifier.)
