One of the slightly negative things about the removal of keying and attunement is that players can now join a group for something without the gear that you normally acquire by jumping through the keying and attunement hoops.
And while you can get decent gear through other means than raiding, doesn't mean everyone does so. In the end raiding (with a group that knows the instance) is still the easiest way to get geared up.
I do wish people would be considerate when joining something unreasonably undergeared - like no one will notice. It makes things harder on everyone else.
