Poor social interection in game

Something that I've noticed a lot of lately is very poor social interaction within the game - even more so than before if you can belive it. A typical whisper for me on my shaman reads simply as "healer?" Now in any case doing so is just highly rude because you're not stating why or even where it is you intend on going, merely that you want a heal bot. At first I would respond with something like "care to clarify?" Only to be met with no answers in return.

But then today I was in a group for heroic CoS which unsurpisingly just happened - quite literally - I was browsing the tabs to see what was going and then an invite just sprung up. I accpeted it and after a bit ended up in tanaris. On my way down on the dragon I got kicked from the group without any warning. When I whispered the leader why he said "You have mostly greens." By mostly hes obviously referring to two greens which are actually pretty decant since I used a leatherworking enchant and engineering on the other. He never bothered answering me again.

Now this might seem like an isolated incident but it keeps cropping up. People seem to think that just because its the internet and you're annonymous you can get away with being an insufferable prat - which you can I suppose. But that doesn't mean you should.

Questions like:

"Healer?"
"Spec?"
Or just sending an invite simply wreek of lazieness in albeit the most basic of manners.

Then again this is an mmo; but it just seems to be going through the roof at the moment. Although the gold sellers are getting politer, now they ask if I'm there before sending me a spam.

Anyway, just needed to vent.
