Ok 343, why? Why have you removed Team snipers, FFA throwback (oddball & Hill), AND King of the hill altogether?!? My friends have the same problem, sufinturtle66, wh1tet1ger22, villoscar, ECT. So it cant just be us. We need these game modes back. Its what we injoyed the most! It was going so great. Every new game mode was great! The way we saw it, it was just a matter of time until you put in griffball! (which REALLY needs to come out). We still have swat, so its obviously fixable right? We just need the game modes back. matchmaking isnt the same without it. So all i’m asking is that you put the game modes back in. We don’t nead anything new, just what we already had, If it IS just us then get a way to fix it. Ive searched this online and found nothing. Explain.
—FIX—
They take out the least populated playlists, fix/improve them and put them back online later on.
Team Snipers and Grifball are both coming after the Infinity Challenge.

I advise you to read the future Bullet-Ins so you know what’s going on

You’re new here aren’t you? You also didn’t search very hard either…
343 is doing something new with the playlists. If a playlist has a low population (which all of those modes did. Very much so) it will be rotated out in order to bring something fresh to the table. Some of their choices have been a bit odd…like keeping some of the current playlists that have abysmal populations constantly…but whatever. If removing a playlist that has around 1200 people on average means adding one that has 6000 on average, that’s what they’ll do.
It doesn’t mean the gametype is gone forever, but if you really want it to stick around, you better play it to keep the population up. When they remove a playlist, instead of just tossing it aside, they take a look at what they can do to tweak it and bring it back in the future, hopefully bringing a larger population.
Grifball is coming on the 28. If the population is awful (which I doubt) it will leave. SWAT has been around forever since it has been the playlist with the third highest population every week (not counting the time when the Infinity Challenge started…but even still it’s up there)
If BTB population were to suddenly plummet to terrible numbers, it would be removed to see what they could do to fix it. No playlist is safe.
Sorry for the lengthy post, but I figured I would try to answer any question you may have.
