I like a lot of what you proposed, the only thing that's coming to my mind is I think you should redo the offensive invocation spells. The reason being is as A rank offensive spells I'd expect something totally out of the box and something far more dangerous than elemental bursts at that point, a lot of those spells seem about B rank? or lower aside from their scaling. I.E. for the fire branch Blue Akashic Fire that would inflict a nasty burn status that cannot be removed by any means with any skills or items and lasts the whole match. Or an A rank invocation that would summon Earth Golems with massive HP pools and such that fight for you. Or a Black Hole spell that deals dark/null damage and pulls every enemy on the field into one spot for you. Or a huge explosion that does akashic damage. You get the gist I'm sure, these are just some random thoughts I'm throwing out. Other than that I like a lot of what you presented. +1
