I agree the focus on atta-boys and perks has skewed things. But there needs to be some kind of scoring system, and this is better than anything else I've seen. At least it promotes offense instead of defense.
But to acheive the "goal" as set out by the scoring system, well, the players have found the optimizations. Horde. HO. Ram. Vultch. Pork. Lather, rinse, repeat. The proliferation of people relying on HO'ing and ramming is getting pretty bad. Some don't care about getting better, but I think a large number realize they can "win" without putting in all that effort, so why bother doing the work?
The impact of a dead barracks in terms of number of affected players gives the porker a lot more power to affect overall gameplay than he should have. Likewise that ground kills are counted the same as air kills for perks promotes the "3-passes and out" runway vultch dweebs.
It's not that the current system is so bad, its that the style of play has been optimized to it and that is eroding the quality of gameplay. So some adjustments are in order.
