Or maybe just give them the goals with the same opportunity the rest of us had to complete them. I'm a level 99 player and have more than the full complement of ovens and so could complete any released goal in a fairly quick manner, but remember that for some new players it's hard to complete the goals within the time period given because they may not have access to the full compliment of ovens and may be "poor" so can't complete the goals quickly. There are also players who are at lower levels who may not have access to the goals since some goals were level dependent.
