throwing this out there and hoping to maybe get some discussion:
what if... some of the difficult-to-get badges in the game gave a stat boost of some kind when equipped...
I saw a person with TEAM MVP, that is 5000 teams helped, I think. Why couldn't they get stun immunity from having that? or why couldn't Elixer Vitae come with a 5% outgoing heal boost added to your base stats? even a modest, tangible benefit would be a terrific way of encouraging folks to go after them...
or what if, a wizard attains two or three of these achievements, those badges could have a jewel socketed in them, which gives the benefit when the badge is displayed? Even a boost similar to the kind you can get from certain mounts would be nice.
