There's a couple of things that you can do to prevent people acting annoying towards you:

The friendly approach
Pass battleground intelligence on to others (movement of enemy players, efc locations, etc) and ask for the intel. Most people will notice that you're a team player and they will be less inclined to act ignorant towards you.

The ignorant approach
Respond with an even more ignorant reply. If someone is trying to blame you then just blame instead. For instance, if someone is complaining about people not defending the AB flags, then order him to go defend one of the undefended flags (farm or stables will usually do). Of course they won't accept orders from you and the undefended flag will fall, giving you an unjustified chance to blame them for the loss.

The really nasty approach
Place a raid icon above the player that is complaining. You'll notice that they'll stop complaining about you, but they'll start complaining about the icon. Either tell them that you'll remove the icon when they stop complaining or be even more ignorant and replace it with another icon and ask them if which of the icons they like better.


The first option is usually all that you need, but some people are really asking for it...
