Where is the need to cap people? Because they have more time than yourself to play so level faster? Because they do not want to read every single quest or bit of text? It is silly to do that as not everyone plays the game at the same speed or even the same way.
I'll happily come back and blast through old content with someone even if I have out levelled it, Remember just because you are running around on your own does not mean you are on your own... the guild is a social one as well as a gaming one.
no no... its not for people getting in front its for people who want to do older raids..... at the right level.. although its will be a walk in the park but thats not the point
