How about to make Hildibrand a BLU in the future 5.1 Hildibrand's storyline?
I think BLU has some of the most weirdest and funniest attacks: 1000 Needles (though we can't do the Cactuar move ), Sticky Tongue, Flying Sardine, 4-tonze Weight... With these kind of moves, I think its the perfect job for Hildibrand.
Not to make him more focused on battle, but maybe to practice it and who knows. Maybe unlock him for Trust system? To include him in Record Keeper and Dissidia NT? (I will always ask for Nael first for this but, hey... why not Hildibrand too?).
And I'm just saying this because I had to. xD (Don't start to say other things about BLU for full job).
