You know what stinks? Getting Smurfed! No one likes that. A possible solution to help fix this problem would include setting a rank requirement for Ranked Playlists. This would also help prevent new players from getting utterly destroyed by high level players.
For example, imagine if you had to be Rank 25 before you could play Ranked playlists. Of course, this would have been ideal if 343 had thought of this from the start as I know many people with smurf accounts Rank +30. All well, perhaps this could help cut down on future smurf accounts; and if someone really wants to waste their time getting a smurf account to level 25 just to smurf high level players than maybe they should re-evaluate their life choices. Lol
Puh... how often do we want to have this discussion?
Rank requirements will definitely do more harm than good for several rather obvious reasons:
1. You exclude new players from entering the ranked playlist. - Sounds awesome
2. People who have enough stamina to play super boring noob bashing games all day will also have enough time to make a rank 20 account.
3. Boosting is NOT related to the CSR but the MMR gentlemen....
You can have a rank 90 that always plays Blitz and then sporadically joins DM team playlists with a MMR of 0.5...
There is only one way this can be fixed effectively and this is by changing the team skill attribution when the CSR adjustments are computed.
Smurfing/Boosting is only really a problem in team games and why is that?
Pair a MMR 5.0 player with a MMR 1.0 player and the MMR 5.0 player will no longer lose CSR - that simple.
So all you would need to do is adjust the team strength estimation by weighting the high MMR players more.
If the team MMR 5.0 + MMR 1.0 is closer to something like MMR 5.0 + MMR 4.0 the incentives to actively boost will diminish.
Sure, the MMR 5.0 player will no longer want to play ranked games with *actual* MMR 1.0 players but that's nothing to optimize for.
We proposed this often enough but there's apparently not much the current dev team can do in that regard.
Please stop these rank requirement proposals.
