I hate shouting of spell-names in general. In the manga they are usually written as overlay to the picture, which means that nobody actually said them out loud.

Why would I shout the spell name into the enemies face and thus give away what I'm doing? To give them a chance to defend? To waste precious seconds in which the enemy can dodge, defend or counterattack?

I'd much prefer for there to be no shouting out, unless it's an incantation that's part of the spell like with calling a Celestial Spirit.
