Considering it is a legendary skin, I expected a bit more changes to his ability designs, especially his ults.
the potions looks like canteens and the triangle spell has a laser pole outline, hurricane could possibly be remade to contain static models of guns spinning around while the other ult could force the enemy team to salute at attention
but there’s a problem of adding these animations to 90 other heroes
hanzo model on the other hand has 2 Snakes for his dragon strike and the scatter arrow looks drastically different, there is sometimes only so much you can do with a hero and still keep its identity, easy solution to this would be to change the spell colours to the heroes that don’t allow a lot of experimenting
simple changes like rehgar ghost wolf color, green orb for the azmodan’s gul’dan skin and so on, average or lower quality skins can be made to look much better this way
blaze isn’t exactly the king of animations and spell effects, but he has an unique looking bunker
also his is anything in your post an actual bug report?
