Remember, to get the achievement Shortcut, you must beat the plumber in under 5 seconds. It is possible to make him fall off on his own, but this doesn't trigger the achievement, even if you do it in under 5.
I really enjoy this game as I never, ever, have to be max of anything in order to do everything. However, the recent grab bag mentality of Kabam selling just about everything is lame. This is what happened to Guild Wars with "Pay For Convenience". Instead of trying to get new people to experience the game the way it should, they're giving you the best stuff for money without effort. I guess people have too much time to actually play the darn game and need the best stuff ASAP.
