I have never been in a group where we refused anyone or complained about anyone because of gear.. ever. Not everyone is a twink. Not everyone wants to twins their characters.
I know that I always love having a rogue in groups. DPS is always a great thing. If you do find that grouping is scarce, try a different class for those times that it's difficult to get a group? I hate seeing people leave which is why we are all posting here but if in the end you are not having fun, then perhaps it's time to go for a while..
