I guess my main thoughts on calling out attacks is that it lets everyone know what you're doing and how to act accordingly. Like, if I did a limit break on someone but didn't call it out, how would anyone but me know that that was a high-power attack (like, in the sense that they would need a potion or something, just to be more dynamic)? I like the idea of doing text in the final version, but I also think for the sake of comprehension, it may be nice to have attacks called out in the battle, if only for our own sakes.
But I do agree, whatever we choose, it should be uniform.
And also, this got me thinking...maybe limit breaks aren't that necessary. Maybe just doing basic attacks would be easier, and still just as fun. *shrug* I don't want to over-complicate it.
