Still... at the very least there should be some incentive to skillful play, rather than just luck in ending up on a winning team. Something to balance the payout. I've always thought it odd that this game didn't reward you for kills in any way.
When Crpg was first released the xp/gold system was based around kills and guess what, it was pretty bad, it basically consisted of everyone spamming mindlessly trying to get the kill on the enemy whilst not caring about teamwounding, everyone beat the shit out of their team mates just trying to kill the enemy so they could get the reward.
Even with a system like the current one, adding a kill specific reward to it will without a doubt make many players more careless about wounding team mates just because they want the kill reward. Also, what about when you do a majority of the damage to multiple enemies but get none of the kills, why should the other guy be rewarded for getting the "last hit" and you get no reward for doing most of the work?. The current system isn't great by any means, but rewards for kills just aren't the way to go.
