I enjoy BLU for what it is, and enjoy the wide array of spells it has, sure it has an "optimal" set of spells, but being as I do not see it as a job I do not feel the need to play it optimally. That being said, I do agree that in an ideal world BLU would be the best of both worlds, but as it stands we do not live in said world. Now let us say they did want to give us the best of both worlds I assume that would require extra development / resources and they properly have already allocated said resources and BLU is properly not even on their radar. I assume no serious questions / changes will be made for BLU until 5.5 at the very least. Since we all know even simple changes can be fairly complex due to the games spaghetti code.
