It is the gear junkies that ruin the experience for me. I had one group where the tank just completely lost agro and Titan came running for me of course. We wipe and then the idiots turn around and say "oh i know why we failed it is because one of us have level 45 gear on". No it was not due to the gear it was due to the teams inability to play their part. As long as you learn to dodge and contribute when needed top tier gear is not necessary.
