No, they pruned a few abilities and combined others, but the end result is that by the end of Stormblood you have roughly the same amount of abilities to use at end game as you've always had...which is kind of a lot.
I don't want SE to go as far as Blizzard did in pruning abilities, but most classes just have too damn many buttons and could learn a lesson from WoW in that more does not mean more complex or better.
