I'd just be happy if they opened up the support skills a bit more. There are literally DOZENS of skills which would benefit other jobs which can't be used by that class. Why? Goodness only knows. Presumably because of some bizarre notion of balance, and yet these skills are undoubtedly useable by the class the job is built from.

So, just because I go from Gladiator to Paladin, I can't regen TP with Invigorate? Does equipping the stone make Paladins stupid? They even removed Thunder from Summoner's cast list for reasons unknown.

I guess that's my biggest gripe when it comes to 'customization'. There is literally none when it comes to skills. You have a handful of ones you can actually equip, and usually less than 5 of them are actually beneficial for your job. Much less than 5 if you're a Black Mage or Summoner.

Either they could give us some new equippable skills, where we're restricted to 1 new skill out of the selection. Or they could open up the cross-class skills to make them actually cross classes. Right now it feels more like an afterthought than any real attempt at character customization.
