Champion interactions.
So Yasuo came out and he has some cool interactions
But this made me think that I practically never hear any interactions between champions even though the match ups happen from time to time.
During a game people rarely use taunts and emotes, especially in lane. There should be some change to make the interactions happen more often.
Something that Aatrox has - an automated line. I would argue that it shouldn't be once per game though, give it a cooldown of ~10-20 minutes for the same line.
And give the same treatment to other interactions.
This would bring a little more life to the game as well as actually use the work of voice actors a little bit more.
