I don't support it at all. The game already has playlists suffering as is and this just furthers it. I'm all for the idea if the mcc had the luxury of a good sized pop but I'm not seeing that when half the time it takes 30 minutes to get Into games depending on what you're playing. Playlist have issues because people cant play what they want in a game that took 4 years to fix after its release LOL. Pretty sure this could only help because people playing are actually getting what they prefer to play. Although the veto system is the right fix, 343 is too afraid to do it because its already been done and worked so well.
What I'd suggest is sure, implement it for now, but as time goes on players will have to untick things just to get games or not play at all. I'd also suggest the matchmaking system to bypass the feature if games aren't found in adequate timing as not everyone has countless hours to waste on searching for a game.
Im aware of the mccs history of issues, it still doesn't change the fact that pop issues are still there regardless of why they're like that.
I'm not in agreement that it'll help at all. You say people will get to play what they want, but this in turn also limits what others can play when part of that pop is no longer around. This is really nothing but a luxury feature to me and the mcc doesn't have much for luxury with all of it's issues now and from the past.
Here's my point. Let's say btb had all 4 games into one package, no one gets to play exactly what they but you have the most players possible so search times are quicker. Implement this feature where people only took one game and you divide your count significantly. Let's just pretend BTB has 500 players in total and you implement this. Odds are H4 gets ignored by most people, I'dimagine H3 would be the most picked with H2 and H1 following. Out of that 500, 200 pick H3, 100-150 pick H2 and H1 and H4 is left with 50 or so players. You're going to always be playing vs the same players, you're going to have different times in the day where searching for games take longer, and in the end you'll have to tick a game you don't like just to play unless you move onto an entirely different game. I don't see how this helps as you're just taking players away from one game to another, essentially the least liked things will be left in the dust and those who do like it get the lesser experience or none at all if the game/mode is dead.
I already hear how swat is non existent in players, doing this just puts a nail on it and the same to other modes. This only truly works if you've got a pop to support it and or players who are tolerable to other games "if" they had to.
