You're missing something with your adjustment. a THM/BLM uses MP which when they run out they have to restore. Also spells at lv 50 cost a lot of MP so if you aren't careful you'll find yourself without any MP to perform actions. Melee on the otherhand have the ability to continuously gain TP to perform abilities as well as combos which save them from using TP. a Mages combo only adds an extra effect to the ability it does nothing to save them MP. The balance is there people just prefer to use THM/BLM because of the pretty numbers but in a fight that may go on for quite a while you may find that the THM/BLM will tucker out after a set amount of time.

Though perhaps to make things interesting some new bosses which could be introduced are perhaps ones that have AOE mp drain or counter mp drain when to many spells are cast on them at once. So if you have 4 THM/BLM in the party and they all cast a spell in a 30 second segment then the last one to cast the spell will be aspired and lose some MP. This isn't to say that having 4 THM/BLM would now be useless but it would just mean that said mages would need to stagger their abilities and find other ways to be useful during combat such as 3 THM/BLM target the boss while one waits for adds or perhaps they go on THM and support the WHM while also keeping an eye out for adds.

Adding the same killing speed will only cause melee to become overpowered because then it turns into, what's the point of being a mage class when my abilities are 0 when I have no more MP, at least on a melee class I only need to use TP to use abilities.

It's just the one thing you need to keep in mind, a THM/BLM strength comes from the fact that they use MP to cast their spells, without said MP they have no battle potency.
