Weird, I've had quite a few. One of the reasons I'm trying out my odd houserule on death -- I wanted to see what happens when TPKs are off the table and instead character death is only when a player stakes it. I may not have mentioned that staking death is something you'd do if you'd normally die, and instead you don't and get a nice set of bonuses but you absolutely, without recourse, die at the end of the scene. That way, choosing death is meaningful, and choosing to not die is meaningful (I get to do bad things to your character). This plus combats that don't always focus on killing the other side first have made for some very interesting combats, as there's zero need for me as GM to be fair or pull punches. I can overstack combat challenges (with proper foreshadowing, of course) and not worry about the fairness of it. All in all, it's lead to more exciting combats, especially for me.
