No, I don't care, I don't feel better winning against emoting opponents than silent opponents, and I never assume my opponent "obviously draws the nuts" just because he is emoting me at the start of the game.
I should emote more often so people think I drew the nuts lol.
Sometimes I feel like i'm playing a different game cause this almost never happens to me.
70% of my opponent will emote hello at the start and GG at the end (I will too), and when something unexpected happens. 29% of my opponents are dead silent. 1% of my opponents actually spam emotes for no reason at all and they get squelshed very quickly.
