A wall of fire is'nt as strong as a concentrated attack, so it does really matter if Enel could dodge attacks and so would be able spare his stamina and power for his own.
You did try to down talk both Ace and Aokiji, so I pointed out some points, showing how powerful they could be, while Enel is likely already on his high and could not rise anymore. Obviously we did'nt see both of them doing such, but your exagaration was needless too. With his power, BB is able to withstand any attack, that's a simple fact. I think it's more likely, that even sea stone would be swallowed up in his void, as seen at Impel Down. Haven't noticed, that you are canceling out your arguments, with your everybody has a one-hit attack theories?....
