In reply to my "minigames are horrible for pvp XP - the compiled whine thread" Didek, age of conan developer confirmed that:
"Some PvP exp reward for the minigames is in the works but won't make it for patch 1.04".
see the source.
I *really* enjoy minigames so I got my hopes up for any change for the better.
Expect that to hit live servers around june :D
