I don't know if they have room to add anymore to the tiers but this would be my suggestion;
Tier1-Host Toast-this would be highlighting the host for each game so the opposite team knows that he can shoot you half a second faster. This would work because Activision won't want to invest any of it's billions into dedicated servers so game is at least fair.
Pro-host respawn is 3 seconds and it's a clip of watching you teabag his face.
Tier2-Random Spawn-this would actually give you some randomness to the game, instead of the known spawns for each map. Such as; my team is over here so they are spawning over there and I'll wait right here so i can get 5 kills in a row without much work. Again this would work in Activision's favor since investment into the game would require money and they can just add to the gameplay and 72 billion will continue to buy.
Pro-respawning right behind that homo who justs spawn camps.
Tier3-Address Validation-for all the big mouth 12 y/o's your real name and address would appear right below your gamertag. and you'll finally be able to prove to the community how tough you are.Accountabilty becomes a very important word.
Pro-You really don't have to have one but lets just say 2 extra frags.
