Infact, you would end up with different sets based on what you are going to be playing, a dungeon set, a trail/normal raid set, a savage+ set etc. It would just be a pain to switch between them.
You can say, well, restrict what they can have. Ensure they have some form of AoE, make sure they have at least X amount of mitigation etc. At some point you have to think, we are basically funneling them into this specific direction anyway, might as well just give them everything they need and balance that.
Blue Mage works because it is designed to be flexible between Tank/Healer/DPS, even then though, there are specific spells that you will find the vast majority of BLU uses. Even ignoring that, alot of BLU spells are just copy and paste of each other, just with a different element.
And only picking 24/28 you could have, you just nerfed yourself for no reason.
The way they do it now is the best way to do it to maintain balance and also to keep the ease of balancing.
