This comment is so stupid i just lost IQ points... It's like saying "Why use a bike, you already have legs?".
Joining a group with the standard UI is rather clunky, but i do agree, it only takes maybe 5 seconds. THE PROBLEM IS THAT SOMEONE HAS TO MANUALLY CREATE THAT GROUP!!!! Type in the name, chose "Questing" in dropdown, chose other options, create the group, having to open the group finder every 5 seconds to invite players, having to manually check if it's just a realmhopper and then removing this guy, and i could keep going. All things WQGF did with 1 click and then forget about it.
All this functionality is perfectly available in game, but it's about as smooth as cleaning your floor with a toothbrush - which i have to remind you IS perfectly doable.
Honestly i cant even...
