The best way to deal with people who pork a base with a hoard is simply accept you've lost the base and not up any planes for them to vulch, they want easy kill vulches more than they want the base. Granted they do want the base but it comes a distant distant second to a good old score vulch.
I don't accept the forcing them to play your way because you want it your way statement from skuzzy. The people doing this sort of thing are eliminating almost any danger to themselves. If the people 'defending' the base think the same way and say the only way to have no danger to ourselves 'manned ack aside' is to not defend the base, what do you then have? a combat simulator with zero combat.
What I do agree with is that theres an arena for nearly everyone, mid war can be very good at times and frequently has a wide spread of good quality sticks and fights if you can catch the right people on at the right time. WW1 is excellent fun and as close to 'pure furballing' as your ever likely to get in terms of gameplay, theres nowhere you can run, I find it funny that quite a few of the people who bleat on about 'I'm for the fight' never visit this arena beyond the first few days.
