But, but... removing chasecams would force matchers to do more than just move, jump, and shoot! They'd... they'd have to think and play strategically! Good luck getting this past those guys.
Anyway, obsblackout already exists. Lock-to-team-chasecam-only (whatever it's called) already exists. But no one plays with them because no one wants to. When some kind of global stats system gets implemented, maybe some standards can be (optionally) enforced on servers. For example, pub/individual stats could only count on servers running a more pub-friendly, standardized config, while clan match stats would only be recorded on competitive servers.
Until then, people will play what they want to play. And the current clan folk seem to have little to no interest in enforcing competitive settings on match servers.
