asuna isnt even that crazy on flash initiators, split 1 he had a very flukey performance and it showed later how he started playing worse and worse, his raze is also god awful and he used up all his lucky flying headshots in split 1
He played way more raze in split 1 then he did flashes. And yes he is that crazy on flashes his kayo util is second to none. That's why they had such big success especially on breeze and ascent this season.
