Sadly in so many ways it's what so many are now obsessed with. I see the exact same in Quake. If you're not hitting 45%+ LG and 60%+ Railgun, you're garbage.
I think thats only part of the picture. Sure, people use stats as an indicator of performance. But the main gripe of most posts I have seen in here is yet again the COD netcode is garbage. £60 to play the connection lottery where the odds appear to be stacked high against you.
Its about fairness. Players being repeatedly hobbled by the netcode / server architechture is just not cricket. It creates frustration and derision towards the franchise. Fine if someone is happy to get ripped off because they feel like they are having fun, but thats really missing the point - the problems still exist even if someone chooses to ignore them.
There is no reason players should pay a premium and be regularly subject to a sub-par performance. Its greed at the expense of the playing experience. Simple as that.
The RRP is higher than probably every other game in the genre yet the online performance is lower. Go figure.
