Are you really that bad a player that you don't realize that PvP gear also bring equivalent item levels but are absolutely horrendous for PvE?
Let's not forget all the idiots running around with items they don't need. I've seen healers having over 300 hit being taken into pugs? Want to know why? It's because people like you don't take the time to learn what's right and what's wrong, and then take whatever ridiculous item they can find, and being bloody carried into content by people that actually know what the hell to do.
Oh, and yeah, those epics are really hard to get with today's welfare system and achievements are so hard to fake. /facepalm
First off, If I am pugging a raid I gear check. Gearscore is good first impression imo. I check there gear/gems/spec to make sure they know how to play there class.
Now if it makes me Elitest if I want my raids to have good players in them then I am sorry. I organize a 25 ToC every week with half guildes and half pugs. I have found that people with around 4500 gearscore are generally geared and smart enough to do well. Now does this mean I don't gearcheck them anymore? No. I still gearcheck them but by having gearscore I can tell if it is even worth my time. Sure I can be elitest because I don't even bother to check people who have under 4k..
I don't know how good you are without ever playing with you. So like I said all I have to know that you are a good player is how you gear/gem/spec your character and by what achievments you have.
