I agree with Div, I think the records of cap gives (more competitive) people a mentality to try to cap as fast as possible without thinking of their teammates.
Sure, you should cap as fast as possible, no one wants to take the flag and stay in the enemies base. But the speed cap record works in a way counter teamplay way. If it worked in a teamplay way they might have said: "Will you help me cap the flag and break the record? Can you hold off the enemy."
In a way that's good, but it's the wrong reason those other guys hold off the enemy. This mentality is wrong to CTF.
As Div said, now that there is 'Race' that's where people can get their sport on and try to beat the records. CTF is not some kind of race trying to beat records.
I'm not saying it should be removed completely (personally I'm for it), but at least try and see how people react. Maybe disabling the feature while saving the statistics so that no one gets mad if all the records are gone.
This is just my personal opinion.
