@Collin: Amusing, but again, if there is no risk, there's no reason to roll the dice. DMs who have characters roll dice to see if their characters can tie their shoes are highly annoying.
I'm not saying there shouldn't be a risk, mate; rather, that there's a severe disconnect between the word Easy and how difficult DC5 (described as "child's play" in the game) actually is. The solution is to rename/redescribe the DCs appropriately.
Incidentally, that would also tie in perfectly with your approach of not rolling for anything easy anyway (which I share and is core to my design of Atomic Highway). By renaming/describing the base level DC5 as Risky or somesuch, you make it immediately clear that you don't roll for anything less demanding (i.e. "easy") anyway.
Two birds, one stone, simple solution.
