What's the deal with all the emote hate?
They're not detrimental to the game at all. This is because you can turn them off. I see a lot of people saying that emotes are useless, but that's just wrong. If emotes are introduced later down the line as rewards for Battlegrounds, it gives summoners motivation to push harder. If you get rinsed in a bgs match, expect to get dunked on with an emote. And if you don't want to see them, just turn them off. I turn them off sometimes, just because I'm salty.
The point is, the hate they're getting isn't really deserved.
