The BFV flag cap doesn't promote team play at all, it just makes capping needlessly complicated. One man on his own can still cap an empty flag in BFV same as BF42. The only thing that changes in BFV is that the cap time varies with the ratios of blue/red team members. So you get this clock running fast, slow, backwards or stopped, that gives extremely useful information to the enemy about whether they outnumber you or not. The BF42 system alerts the enemy to your presence, but doesn't tell-tale on the size of the forces.
Like the diamond mini-map, the crappy BFV class system, the disappearing foliage, and the helis lifting tanks, the BFV flag cap is a worse-than pointless gimmick added in an attempt to differentiate BFV from its predecessors. Nothing to do with gameplay at all. Anyway the BF42 flag cap system already encourages "teamwork" because more attackers in a group are more likely overcome any defenders, then cap the flag when they are dead.
