Could you contribute something else?
There will always be trolls looking to be funny. It is inevitable, whether or not there are emoticons. And to avoid spam, you can simply set a limit on how many times you can put an emoticon every x seconds or minutes.
Haaaha I automatically imagine a spartan dancing when he kills another spartan and gets shot with a skewer. 
I have never seen a middle finger in Halo, ever.
On a blog post they said there will be none unless Joe makes Master Chief dancing cannon. But I mean Master Chief doing a tpose and Never Going to Give you up that I have seen because I have the Master Chief skin and Never Going to Give you up is cool. Also Master Chief doing blinding lights is funny af tho. But emotes don’t need to be in halo. Arby playing the halo theme on a flute would be epic.
I don’t super agree with the idea that emotes would be unrealistic. MP is essentially a military wargames training simulation featuring highly trained soldiers. You’re telling me soldiers never show boat and do goofy stuff to rub it in the other squads face when they win?
That’s kind of what I was thinking. So maybe some hand gestures etc., but I’d rather them not do the orange justice etc.
Dances are silly IMO, but as someone else said, tactical gestures or even weapon poses could be appropriate.
Emotes do not belong in halo, IMO.
I mean… We’ve kind of got our own set of community-defined emotes already without needing dances or any new system. We’ve got T-bagging as a way to brag (not condoning just pointing out), jump spamming/Ghandi hopping to say hello, melees for high-fives, etc. I’d rather Halo be innovative in places where it actually matters than requiring 343 to backtrack and invent a whole new system when their time could be spent making the game as polished as it can be on launch day and improving the game after that.
As for tactical emotes we already have a soft callout system provided in Infinite via the voices of our Spartans and personal AI (even if “over yonder!” isn’t that helpful ).
I would like for funny/meme stuff to be confined to armors and weapon skins. I don’t really want emotes. I just don’t think they’d fit Halo very well.
If you want Spartans dancing, along with Butlr, and other whimsical stuff, you can play Destiny 2
If you teabag after getting kills, you are not against emotes.
I dont want emotes in any capacity, aside from T-bagging as thats linked to a in-game action, crouching.
I don’t see how they could be implemented in any meaningful way. Maybe a way to use the spartan’s voice in the game rather than just scripted lines?
Disagree.
Normal in-game actions should be the only way to communicate with other players. In Halo multiplayer, rapid crouching is a universal sign of friendship. Unless, of course, it’s over a dead body.
Well yes I kinda am. I don’t need an animation or set of animations that will likely be very cringy to communicate with my team. Like I said, there’s already a bunch of ways to do that that are faster, more well-known, and easier to use than to pull up a new menu or use up a perfectly good keybind.
I enjoy occasional teabag but I am not in favour of emotes 
.
Because copying other games has worked so well for Halo in the past, right?
Frankly, I don’t see a world where emotes are implemented where it doesn’t, eventually, get out of control. They may start with some somewhat reserved and “grounded” ones, but since the whole design of Infinite seems to be expandability, they’d add more over time, and to make the new ones stand out, and to feed demand of players from other games who are used to their avatars being able to floss/dance/etc., they would end up adding goofy/stupid ones eventually.
I’m glad they seem to be taking a broad “steer-clear” approach on emotes in general. It’s one of the more encouraging customization decisions I’ve seen for Infinite yet.
I get what you mean, I do think tactical emotes could be cool but I don’t necessarily think they belong much in a halo game in general. Their decision of not doing any I think was the right one, we do have poses for when games start and end so to me that is more than enough.
