Remember mist energy everyone?

Anyways is it possible drop rates were more fair/plausible when mist energy was around?
In theory since you were supposed to play less you should encounter more kats/rare drops/ item drops/ scenario rooms.

Now that we can play as much as we want, would they tweak the odds of finding those to be less?
You're supposed to play more often, but who really is going to play that much?
