The game has only been out for 24 hours and players of Call of Duty: Black Ops 4 are already complaining that something needs to be changed: the emotes. Several people have pointed out on social media that you can use an emote in the middle of an animation to peek around a corner and gain a slight tactical advantage in case other players happen to find their way to the other side of a wall, as you can see in the example below.

It's a legit complaint and one that could end some multiplayer matches pretty quickly if your final kill relies on a corner shot. But the game is so new, there's no way of knowing how soon players will get a new update for it that will fix bugs and make changes. For now, you just have to deal with it.
