This is definitely a game where you have to work together. I tried going it with just my brother and we got largely hammered, especially because everyone else on TR that night must have had the same plan in mind, vs NC who totally had their shit together. They were handing it to us so bad it's like TR wasn't even there. With battles being so large scale you HAVE to work together on an equally large scale (which I think is a great element) or you'll just spend all night pissing in the wind.
I do agree that base caps are largely pointless. If one guy manages to get to a cap point for just a few minutes the point is captured. I think it'd be better if caps took like 20-30 minutes at their fastest to encourage longer and better planned battles.
