so i guess your saying that kisame is to over confident that he wont use itin terms of logic he won't use it. I am saying if he does not kno about c4 Kisame would not try to use waterdome against an opponent who flies. that is just logical, just think about it. All i am saying is that if they were to ever have a real 1v1 battle without knowledge about deidara's secret tech(which only tobi knos) kisame would not use water dome becos he would try to use long range attacks and not sit in a water dome when his opponent is fighting. But wiith knowledge kisame takes it without that much difficulty. And first of all kisame won't just win if he is just in the water dome, he has to go for the kill not just stand there and water dome's which he uses only when there is an opponent inside and kisame can absorb his/her chakra.
he never loses his guard i am thinking logical and i still see kisame winning
i mean why not the water dome can reach his flight and i still think kisame will use it in the fight and he doesnt have to just say their the dome can move so he can catch up to deidara plus the water bullet the big one absorbs chakra and could absorb the c4 if it wanted to what will deidara do against that besides kill himself from c0 you are kinda acting like deidara has knowledge on kisame as well it sounds like at least idk
