In another thread we're chewing over whether we (they) can prevent players from grubbing for their most, best dice, or shame them (us) out of it, or whether we (they) should just roll with it. I think I have a better idea:
Pay people.
Use a reward instead of a behavior. If you roll a sub-max die from one of your Power Sets, take an XP. If you skip rolling a die from a Power Set entirely - not because it's Shut Down, but just because for crying out loud, enough with the adamantium claws already - take a Plot Point*. Or something. I'm open to other reward options+. Make players want to mix things up a bit. We already do that with other aspects of the game, to great effect.

* No, I do not care that this is every bit as good for the player as rolling a D4 Distinction while making it less likely that the player's roll generates a Doom Die. I suspect somewhat smaller Doom Pools make for a better gamel.
+ No, there's no "sauce for the Watcher" option here. You do NOT get a new Doom Die for rolling fewer dice than you could. I mean, obviously I'm not going to come to your house and stop you from doing it that way, but I think it's a bad idea.
