Honestly, I'm more bothered by the "Enhances [x]" traits. I don't disagree about Flash being made baseline, but aside from that, trats evolving your abilities makes sense.
I'd make T1 of Enhances [stat] traits just be a percentage base. 10%? I don't know. Could be geared or ungeared. Could/should factor in your bonus point allotment.
For GLA, I'd add "Manapart" - Mana restoration is increased while under the effects of rampart.
For MRD - TP costs are halved while under the effects of Bloodbath.
For WHM - Your regen spells generate less enmity.
For ACN - Nearby targets gain a boost to a related stat while a pet is out. (Ifrit STR, Garuda INT, Titan VIT, Eos MND, Selene PIE)
That's not to exclude other jobs, just that I really don't know much about them
