I joined a while ago, but then I forgot about my account and I just came back yesterday. My class is Rancher and my planet is Reiflem, does that have any effect on how I play the game?

Welcome to Res :) To answer you question, being a Rancher allows you to hatch up to 3 eggs per day. Merchants can only hatch 1 egg per day. Ranchers also receive a slight bonus chance when it comes to hatching colors. You can also open a Rancher Shop, which merchants cannot do.
