Rainbows? Those are gooooood eating. I use to love fishing for rainbows and speckles. I'm the only one in the house that likes fish though so, unless it's canned tuna or frozen fish sticks, no go.
Porking is bombing objects, radar, ords, troop, fuel on a base with no intent on capturing it. Sometimes it's just used as a term to describe the act of bombing bases. Killing the hangars is termed "toolshedding". Welcome to the colorful world of AH.
In the main arenas, winning the map is the goal...in the AvA the battle is generally the goal, at least it used to be. The big issue is that the AvA has to be reset manually, there is no automated map rotation like the main arenas. So if someone wins the war and the map resets, someone with admin privileges has to go in and manually put it back to the way it's supposed to be for the setup.
