I have to agree with superman on this one, the flash is way to long for the benefit that it gives off.

I don't really have a problem fighting through the flash, but it is an inconvenience. I use it more as a last resort simply because of the flash, but maybe if it connects with someone have no flash, that way the fight is still fair. And if it doesn't keep the flash at 5 seconds as a penalty for spamming.
