Job action combos one button

[Shurrikhan]

None of this makes sense to me. The fact you can't play bard is unrelated to the fact its filler is only one button, you just don't pay enough attention to procs, but you wouldn't pay more if you had 3 buttons to press instead. I... Don't know if you're seriously thinking that "having more things to think about makes it easier to think about even more things".

No, that one can make sense. If your moment-to-moment decision-making is barren to the point of painful tedium, it can be that much harder to make ready for the infrequent, larger points of decision.

I don't see how a rigid combo (i.e., any that takes up more buttons than it has actual available decisions) would provide moment-to-moment decision making, but it can at the least help one keep track of what GCD one is one, especially so long as the pull and one's rotation is consistent. If X mechanic always happens on/with Y (GCD) button-press, such helps with subconscious tracking of the fight. I wouldn't force that bloat upon others or reduce actual available kit complexity for so little, but it's something.
