I guess damage cooldowns are just boring "press x for y stats on a z cooldown" too with no interactions to your class toolkit too, right? Burst windows don't exist, right? Haste proc doesn't change how fast your rotation flows or your DoTs proc, crit doesn't increase your "on crit" procs. This is just disingenuous.
I'd take more gameplay variety over "here's your rotation set in stone, have fun repeating it for over 9000 times in absolutely the same way".
