While I do wish for a couple more playlists, truth is the numbers hurt. Every other Halo or FPS gave I've played has 75% of it's player base hanging out in a slayer game type and 15% in a secondary favorite playlist while the dregs of the population play a few other playlists. Some exaggeration here, but, by the numbers, adding more playlists caters to a minority.
So you make up some numbers and then admit that you're exaggerating them lol.
That's NEVER been the case when Halo was successful.
First off, no playlist ever had 75% of the player base in one playlist. Even low-populated playlists still had a large amount of activity, and if not they were removed. And you understood why it was removed, because it just wasn't popular. The problem in h5 is 343 has removed the popular playlists as well.
Secondly, adding more playlists doesn't cater to a minority. It gives us more content to play. So yes technically that lessens the population in a playlist if you only had one to choose from previously, but in no way does it ruin it. However, I can understand if Halo 5 isn't having as much success as they'd like and even in limited content, numbers are already low, so they wouldn't want to do that.
But as for me, I'd prefer waiting 20 minutes to play a game that I enjoy (even though that's not how it would be if they added another 5 or so more playlists), rather than playing something I don't enjoy as much over and over again, or not being able to play it at all.
