Guild Wars 2

It looks to me like all of the current balancing effort is going into well used skills and traits. I think that build diversity would best be served by buffing skills and traits that are seldom or never used until they begin to see some usage.

Doing so would incourage build diversity and may just solve some of the current balance issues, or at least make them less of a wide-spread issue.

And would also begin more power creep which is never good.
