I believe it will be nice to have a character builder webpages somewhere where you can plan your char selecting passive/active/skill abilities.
If it will be ever done, it will be nice to be able to retrieve those in some way (i.e. a copy-paste link that you can save) and the capability to add some free text notes (i.e. highlighting stats you shall looking at or specific gear item).
For gear item if it will be easy to do (i.e. the item database is easily accessible to create a webpage) it will be awasome to add this as well in the same planning.
In this way you can really paint what you want to achieve and what you need to get, min maxing your chars.
My 2 cents
