Greziz what are your interests in the game? In the AvA all it takes is 2-10 people to make great fights. On the other hand once number start going up and there is no clear objective like the missions that are run there it does just turn into a big furball and unfortunately that's when all the HOing and ganging starts. Because once one people gets HOed or ganged they start doing it and it just starts a chain reaction. As for base taking, while rare in the AvA, do sometimes happen.
The people that populate the arena nowadays are looking for mainly fights but don't let that stop you from coming in there and doing what you want. Everyone has their own idea of fun and the only person that can stop you from enjoying yourself is you. Don't worry about what others are doing or saying. If you don't like what someone is saying on 200 just squad them and go on with your fun.
I'm going to setup a mission for this Thursday since Wednesday already has something going on. If you like flying in a bomber raid, escorting the bombers, or trying to defind against them all at historical altitudes then I would suggest joining in.
