How exactly would you define the word RULES??
If someone behaves in a fashion that irritates/annoys others, or otherwise goes against the 'norms' of a controlled setting and gets 'called out' for it ( and according to posts here, should expect to be called out for such behavior ) then isnt that breaking some 'rule', written, imaginary or otherwise?
If there is no rules, then why should anyone 'expect' to be called out on anything? Are there rules or not? If not, then everyone should just STFU and fly.
IF its ettiquite you are enforcing...when exactly did the arena become manned by a flight of Amy Vanderbilts?
Rules, ettiquite, you are just playing semantics.
Fact of the matter is just like Baskin Robbins ice cream, HTC provides many flavors of air combat. Not everyone likes the same flavors.
Now we can tell each other how good our favorite flavors taste, and invite each other to try some or our ice cream....and have a ice cream party. The more the merrier. Or, you can be a brat and when someone goes in to take a taste of your flavor, ya smush the cone in the new kids face.
Just dont be surprised when no one comes to your next party.

It amazes me that people pay to play in a MMOG - a massively multiplayer online game - and are unhappy to have to deal with multiple players! Sounds like they prefer small, controlled envorinments - like those provided by a box sim, or a private server game- not a subscription based server hosted PUBLIC game.
But some have elected themselves virtual 'Vipers', enforcing the Top Gun RoE - 'this is the hard deck, this is the alt, climb no higher, dont enter fights without reservations.....and while they may not be abusive and warrant ratting out to HTC with screenshots and email, just like a little gnat in your face they become annoying enough that you just leave.
If you go back and read some posts here, there are AvA regulars that openly prefer the small attendance - in fact someone said they are happy with 10 players - sounds almost like a H2H room to me.
Judging from the tone of such posts, it seems we have answered the question that this thread originally posed - Why is AvA always empty? - Because the regulars perfer it that way, and do what they can to make it less than hospitable to newcomers, or anyone who doesnt play by the rules..er.....follow the etiquitte of the arena.
Now, on what side of the dish does the salad fork go again?
