Personal Motto: I may not be much good but I enjoy myself.
Some views on Blood Bowl ethics:
Stalling: I don't blatantly stall for two reasons. It's unrealistic (what fired up and not particularly smart Blood Bowl player would loiter around an inch from the line trying to run out the clock?) and I believe it makes the game less fun. I'd rather score and then then test my defence against a swarm of desperate opponents than hang around for two turns and score on the final turn of the game.
Fouling: I rarely foul, and then only for short term advantage. For example I won't foul your Wardancer just because he's your best player, but I WOULD foul him if he is the last player with a chance of stopping me scoring a game winning touchdown.
