Unhappy players is a game issue.
Wait, you think that I am advocating an account wide exp pool? I'm not.
I'm discussing validity of making some of the huge character specific grinds account wide to encourage people who want to play alts again. Be it reaper points, past lives, karma or just something. I showed that making a reward account wide is not inherently bad by pointing to BTA and unbound rewards, both of which are generally popular and one of which you even advocate yourself.
