Well, i don't think he meant something as detailed as "a masenko is 5 secs away from u". I think he means what he says.
An exclamation mark at the top of the hud or something.....and waht do u mean hear a kamehameha or masenko, you only hear that if your close to the person saying it and im pretty sure none of you really hear the beam coming *especially when your playing music*.
A better idea (although i don't know if it is possible), you only get an exclamation mark at the top of your screen if your pl is a certain amount over the person attacking you. In the show, weaker people would hardly be able to read an attack coming towards their way from someone a lot more powerful than them.
Take for instance, when vegeta killed pui pui in the majin buu saga, taht dude was way to slow to see any of vegetas attacks, thus not being able to block any of the attacks.
This sounds like a neat option, although i don't think it is needed. I do think it adds alittle more to the game if it works the way its suppose to and doesnt ruin gameplay or anything.
This is just an idea, so dont get butt hurt or anything.
