The reason we use Emotes is to easily convey an emotion/feeling when something happens in-game.
And yet we've been getting these MSI, YOTD* and VS Emotes that are just the icon of the event. What will I ever use them for?
The Evil/Good Christmas cookie was the one Emote that hit the mark, It's a way to express a bad/good deed.
I don't like to complain about free stuff, but I think Riot can do a lot better.
PS: While I'm at it, I'd much rather have lvl-up Emotes be Icons instead, and if you really want to give us Emotes, create some sort of character like Helmet Bro related to the leveling system and have him evolve with our "legend level"
