There's definitely some consolidation that could be done, even if you don't do the combos...
There's some skills that you won't, or in some cases can't use unless something else was used first.
Like, with red mage or bard, the proc skills that basically replace one of your skills with a better one while you have the proc.
Those could be made so that the skill becomes the proced one.
And summoner, deathflare can't be used unless you're in dreadwyrm trance, and it ends the trance.
Considering pressing the trance button a 2nd time just ends the trance, there's no reason the flare couldn't replace the trance button while in the trance.
