The only problem I have with them is that you don't have to fully ADS into the scope for the bullet to fire dead center. That is what allows people to abuse auto aim in close quarters where sniper rifles should really have a disadvantage.
Snipers would be a slight problem if it weren't for the maps catering to SMGs and the millions of flanking spots on every map including the two maps that cater to snipers. Quickscoping is easy, but the ADS time doesn't make it as viable as in the MW games.
