Hero skins come with new powers and abilities!
When you change the hero skin, the hero has abilities the go along with the new skin ie: Ice Queen shoots shards of ice and freeze or slow it’s target. Skeleton king spawns skeletons like witches. The point is the skins are cool but some functionality would go a long way towards depth. The people who are getting the skins, are the ones who are buying the pass and have spent money on this game for years. Anyway, I believe an opportunity is being wasted to innovate the hero’s skins with abilities that fit the theme.
