Speaking as the person who is actually in the process of constructing an inventory and stat system, I have to say that some of you have really nice ideas, others have very impractical ones. However, it should be noted at at the end of the day, we're not going to be able to please everyone.
The idea the MS:S team is running with now is to use a singular base "level", as in you will be able to level up and apply points like in many other MMO games, with a single exp total, etc. This will still allow for JoaTing, but you won't be able to master absolutely everything. MS:C is more "Master of Everything" than JoaT anyway. It may be a little plain and overused, but we feel it will work somewhat better. It will also make XP awarding and such less complex from a technical point of view.
