Something is missing.

Talent trees serve no purpose but to give the illusion of choice.
People will also expect the spec system to go along with them.
The spec system goes against the whole principle of FFXIV in that you can play everything on one character.
If you want to argue and say "oh but they can just make it so you can play every spec as well" then what was the point of wasting the time implementing the system in the first place? and not just working on new jobs and expanding the skill sets of the current ones.

Everything you are asking for can be implemented better, faster and with more balance by removing the fake choices.
FFXIV is streamlined and because of that our only real balance issue at the moment is PLD vs WAR in regards to alex savage at least its the only one that I'm seeing regularly anyway.
