I don't agree with this idea. Sorry to ramble on about things that have already been said, but raising the number of hatches has the potential to be distastrous. Think about it: If we raised the current Rancher hatching limit (Three hatches per day) even just by just a few more (Let's say not, that it's five), you will have a bigger chance to hatch a colored pet. Now, this may seem good, but this will majorly decrease the value of colored pets, plunging our economy into deeper distress than it already is. Make sense?
As for raising the number of forest searches, I agree with what Yoshi said. It was recently raised, and I think that it's fine the way it is.
Sorry 'bout the rambling. xD
