Actually no, not what frog insisted, I grouped but only with folks I know. I mainly soloed but did do friendly groups because pick-up groups tend to fall apart very quickly and crappily. I went into several of the end-game (oldschool) dungeons and reached lvl 64 and now will wait for the next expansion before reupping to check it out.

Raids in WoW are very player friendly usually Try the old school Everquest raids out some day, those were fucking hard as nails.
