One of the most frustrating things about this game has got to be the fact that almost all the new ovens require oven elements. All my other parts are sitting there, wasted. You'd think they'd at least put in SOME effort. They're clearly capable since they do it with Restaurant Story. I'd rather have 3- 4 types of required parts in smaller quantities. It gives me more of a challenge. At level 99, it is incredibly mundane to go through the challenges now. I always have oven elements stashed, and then whatever new part they create is basically useless after the challenge because they don't use them for any newer ovens.
Anyways, my rant is over but I really don't think this is a crazy request.
