Ultimate emotes that change with skins
I think it would be great if there were some emotes that actually worked with certain champions. For example, what if there was an emote for an Ashe ult that you could ping and it would look different based on what Ashe skin you were using. I think that this would be extremely helpful in communication in teamfights as well as look cool.(The emote could even look different based on your location and where you are pinging or what direction your ult is flying if cast)
These emotes would be champion specific so people could not troll/grief with them causing team confusion/. This could be done by allowing players to create a default emote page for all champions that don't have a special emote as well as a page that would be used automatically if you have that champions emote.
