[Suggestion] MoP style talents!
Hello. I've played this game off and on for a few years and while I enjoy it, I've always (not exclusively to this but still) that FFXIV's jobs felt as if they were a bit of an on-a-rail experience.
You play Warrior, you are a tank. You play White Mage, you are a healer / off DPS. You play Black Mage - you are a BLM that uses the same rotation as anyone else. And unless a player finds something others haven't, such as a way to squeeze in an extra cast by stacking speed, there's really no variety in how you play or build your character, and this makes for a fairly dry playing experience at least IMO.
So I suggest as the title would imply, a talent system akin to what WoW's Mists of Pandaria implemented.

Basically, for given levels, let's say 15, 30, 45, 60, 75, 90 (note this is totally changeable but still) we would get a talent point to choose a major talent for our class with. Let's say in our example we are a Warrior. And with our talent options we could either build ourselves to be Tanky, DPS, CC, AOE damage oriented, etc. What this does is open the door to how a person could play their Warrior and maybe even let them play Warrior as a different role such as DPS with the correct talents. Or, say a given raid needs a particular CC or lots of adds. CC/AOE spec could be viable there. Of course, you could reset your talents when needed. Perhaps from a tomestone item.
Honestly, implementing something like this rather than 2-3 extra jobs for a new expansion would offer players way more in terms of gameplay value because we have a lot of classes as is just a massive lack of diversity.
