wow, its looks amazing 
Anything required to get the Quest Mastery Cape would be based on post-quest content, IE, you'd be able to go for it whenever.
It was supposed to say "to get the tasks done", and "most" instead of "all".
Currently, the Quest cape is 100k short of requiring 2 99's worth of XP in skill requirements.
The only other "mastery" cape requires nearly EIGHT skillcapes worth in XP.
Forcing much (not all) of the post-quest content to have high level requirements would give it much more worth than a normal skillcape, warranting a change. Or at least giving it a reason to exist. 
Besides, I'm going to start refining the list of requirements to more specific things (including things that haven't been added to the game, such as "defeat XYZ in the dominion tower" and such). The level requirement was just a last second addition.
Yeah, same here.
I REALLY hope they do something like this.
In fact, I'd like to see the normal Quest Point Cape have a different model than other skillcapes, seeing as it's not even a skillcape at all, really.
