I've never really encountered any bugs in Conquest, and I don't agree it killed the population. Do you mean that people leave the server once Conquest comes up? If that's the case, then I'd have to agree. The maps are too big and the rounds too long for the population (NA, that is).
However, if anyone is going to put the effort into taking it out of the rotation, I can't help but feel that time would be better spent improving it. It's probably the closest thing we'll ever get to TDM. I think with a more linear design, flatter maps, and shorter distances between caps, it could be really fun. Also cutting the time down from 25 minutes or whatever it is to a more manageable 10 minutes would help a lot.
