Let's not confuse what we wish it was like with the reality.
I don't want to get vultched incessantly, but will endure it to save a field. Failure to do so is tantamount to giving up. This is what is not being explained by anyone; what other choice is there for an isolated base?
If everytime 5 cons roll up on a field with ack suppressed we all ignored the base, yes, there would be no endless spawning, and the capture could occur uninterrupted. But where is the game then? If we have to willingly surrender any base that has dead ack and is not a quick flight from a friendly base, where is the game?
So now, imagine in our 3-country setup 2 big sides jump the small side. Down to 3 bases, should the low side's pilots just sit in the tower? This seems to be the thought, and I can't fathom it.
All this is soon to be moot with the advent of vehicles and destroyable spawn points. I am for closable fields, make no doubt about it, but as long as I can launch, I will. I am not about to sit in the tower and watch the arena become the playground of the other 2 sides.

Again, this is not what I wish was, it's what is.
