Don't kid yourself. BLU did not work well in XI. There were only an extremely limited number of spells you actually used. The rest were only used for unlocking traits. The rest, never used at all. SE just got done with their attempt at pruning unused abilities, and you want to add more?!

Second, again, don't kid yourself. Choice in an MMO is a lie and a myth. The playerbase will find the most optimal combination of a spell list, making any other combo a source for elitists to talk down to anyone else. The players wi then complain that X spell is too weak, and never used, etc etc etc...

The truth is that Yoshi, while not percect, knows a whole lot more about game design than 99.9% of these self-proclaimed armchair devs. They have no idea what they are talking about, completelg clueless to the fact they don't even know what they are asking for.
