You're more likely to actually land kills while playing objectives since, you know, people are attracted to objectives in objective-based play. These modes should encourage teamwork. Plus, in something like IB, you get early shutdown games if your team is dumb enough not to hold points, since even if you're ripping it up, a 2/1 deficit on control points can still give the enemy the lead if there's one or two idiots on your side getting killed constantly. Roaming solo is just asking to get ganked by groups. I hate it when some idiot is sprinting off on their own, only to get picked off.
