You lost 90% of the abilities you were able to equip on another job in 1.0. And the remaining ones now that are actually cross-classable are imposed with cross-class restrictions here and there too. And the ones that remain from that significantly shorter list for your job are, unfortunately, often times exactly the same in potency as an ability you might already have, without being able to use them in a combo, or arent really all that great. There's maybe one or two abilities per class that might get some use as a sub.
Also mages, Thaumaturge especially, no longer have a lot of spells available to them, just a handful of them now. No more full element list and the ability to boost specific elemental affinities as far as i know. Just Stone... Aero... and the tier 2 versions of that. Doesnt really matter anymore since the elemental resistance on monsters got thrown out the window too, but it's still a shame somewhat.
Classes/jobs and abilities have been kinda stripped to the bare basics, but there's a chance that might work out for the best. Atleast it means that not every single job is going to be using the same abilities regardless, although i was kinda in favor of that.
