The ranking system would need to be perfect in terms of matching within the same division for this to work.
If it did, then that could work. AR and radar starts for your placement matches and if you are in Iron and Bronze, then BR starts for Silver, than no radar for Gold and up.
Forget that. Just because you aren't good enough to be ranked higher, shouldn't mean you get stuck playing babbys first Halo.
I'm shit, I'm not as good as I was, I have worse eyesight, it's hard for me to see things clearer for headshots, and even I don't want AR starts. It's not about skill or not landing headshots with the BR. It's that the AR is a low skill weapon where you barely aim, just hold down the trigger and bam. With ADS, it's never been easier. Same for SMG.
BR starts will probably be worse for me, and I'll get my ass donged on, but at least I'll have a capable weapon, one that can help me teamshoot or be able to handle multiple situations, especially if I go down a man. Don't know why so many like AR starts. Where's the fun in the spray/pray game play? With killcams, you can easily see how many are just waiting scoped with an AR because of how powerful it makes the gun.
