It's a good idea to some extent.
It would be nice to see some kind of SBMM for a special mode.
The Initiation mode that's been provided for beginners is certainly not doing the job, because it has no limiter at all and is just high rank players farming bots and easily killing any noobs that actually try and use it as an actual form of initiation to the game.
It's always funny to see people come and fight against any kind of SBMM. The only people that really hate it are the ones that like to noob stomp and/or get their troll-lolz farming kills with vehicles.
They appear to think it's much more important for them to have a chance to have a relaxing time getting easy kills against casuals than it is for the other 99.999% of players to maybe not die every 2 seconds.
