Do try to remember that any new abilities will have to be balanced with the as-yet unknown abilities of the new jobs. :P For all we know the entire system could change! Not as drastically as WoW does in-between expansions, but the possibility exists.

Also, a couple people have eluded to it, but Classes will be getting new abilities as you level as well. Not just the jobs every 5 levels.

I support Burst (It would apply Thunder III. The only difference between the Thunders is initial damage, which differs by 10 potency each, and the time the DoT lasts), and I'm amazed MNK hasn't gotten Chi Blast, yet. Would love to see a damage-oriented Fairy, for when overkill healing isn't necessary and obviously SMN's are getting more Egi's. :P
