Getting new actions for your favorite jobs is great, it serves to keep people's interest in said jobs. The problem arises when more and more actions are introduced with no way to solve bloating.

I'm sure the FFXI crowd would argue that there's nothing wrong with too many skills, but you also didn't have to move during fights in fights.

I know a lot don't like to see the comparison, but I believe it's worth, as it's one thing WoW did right. In it's latter expansions, WoW sought to combat ability bloating, by combining abilities that had similar effects/actions or just straight up swapping out older abilities for new ones. If with each expansion that FFXIV gets, possible new abilities will arrive, something needs to be done to decrease action bar clutter.

As an example, simply because I play DRG, impulse drive and disembowel can be combined. Impulse Drive would have a higher attack potency to make up for the lost step in the combo, as well as apply the piercing debuff. That clears up one slot on the action bar, while still keeping the DRGs core mechanic.
Do this with each job and SE would have an abundance of room to work with in terms of new abilities.
