As a game developer (of a collectible card game) i found strange that even elf teams are motivated to run the ball instead of passing it. Currently i beleive 95% of the drives are running drives. My opinion is that diversity equals fun, so i beleive the closer we get to 50% the people will enjoy more and more playing this great game.
(To show the truthness of diversity=fun, please imagine if every drive would be exactly the same. I bet you would be bored, and leave soon. Btw i beleive this is the reason why clowpomb is hated. It is too strong, thus happens too often, so people got bored and frustrated.)

My proposal for rules change is as follows. Change the mechanic of the passing skill, so that roll both dice at the same time, like with 2 dice blocking.

So if you have a reroll, then agility 3 quick throw will be as risky as blocking without block skill, and agility 4 quick throw will be as risky as blocking with block skill.

And because there will be still opportunity to intercept, and catching the ball would be continually a liability, and longer passes would be still a challange, i think running would keep an edge, but the passing game would at least motivate a few more teams to throw the ball more often.

Additional benefit of this change would be that it would eliminate another frustration. Imagine when you need to roll a 3 to pass, and you roll a 2. Then you chose to reroll, and the result is a 1, and a fumble. My proposal would eliminate this too, and there would be also no need for the "do you want to reroll the pass" textbox.

Finally i would like to state, that my proposal would add a lot of mechanical flavour to the following players:
- norse thrower
- amazon thrower
- skaven throver
- orc thrower
Those players are runners really, but with this minor change their name would become legitimate.
