IMO vulching is a part of the game frustrating as yes but it was done in the wild..and is combat...what I find takes it from the game is when this is a sole source of combat for some....when there is absolutely no intention of trying to take a base they just come in with their fast planes and big guns remove ack and pick off planes...sometimes even fighting like a pack of hyenas for the one upper who is willing to offer a fight if they will just let him get up and then merrily trot off home...sometimes one or two less but that was their objective...now that's their right to do so but I don't really pose that as combat....that's like going to the supermarket and buying a fish and calling it fishing...but that's just me...
Agreed, and worse yet, when there finally is resistance, they run away to another undefended field, to vulch the 1 or 2 people who are there first to stop them.
At its core, its a very similar behavior to people who refuse to fight unless they have a numerical advantage. You all know, the guy who runs from a 1v1 to then turn and fight you when he as 10 other friendlies to help. In my book, thats not 'sport' and its barley combat. Its just cowardly behavior that detracts from the game, plain and simple.
