I agree with you to an extent. While it's so much easier and better to just use marks for materials I wish that was just an addition and not a replacement. The PvP isn't bad in this game, but what incentive is there to play it? 3 marks for a win and 2 for losing? No real incentive to win there PLUS the rewards are terrible(and that's putting it nicely). If they gave you 5 marks for a win and 2 for a loss with Tiger Strike rewards I'm betting people would flock to PvP.
