Yeah and I think, the more people are stating they want some kind of reward for that, the better the chances are of actually getting one. Btw. I´m saying that as a casual who is scarcely raiding these days (Although I often did in 2.x). In my opinion it`s a matter of respect that highly skilled people get the best rewards. Being an elitist about it, is a whole other matter, which also should be addressed.
I can understand that they complain but there is a way for them to receive this gear: Get better.
In my opinion, if there was this kind of reward, more people would try to improve to get the best gear available. And even if they would fail getting it, simply trying to would bring their skills to another level. Which I think would make them feel good about themself too.
On another note: No, you don`t really "need" the ilvl 270 gear. But being able to have it is incredibly nice.
