Base capturing is fine. It creates an objective, and due to the competitive nature of some in the game, they feel the need to defend. that equals action, which I'm all about.
When a horde gets rolling, those that care about score disappear from the defending base leave a hand full of die-hards to get creamed, as multiple bases get rolled. That's usually when the whining starts.
I think WILEY has it right, the MA is like herding cats. No one wants to be lead, but base capturing (and defending) takes a plan. But who is making one? Who is in charge? No one.
So If some squad or group or horde forms up and have ANY kind of organization, they can roll the whole map. I can't stop them by myself, so I find a away to find to targets and do my part.
Roll on.
