I think, that it is quite discouraging for low ranked wizards (When they have a low ranked pet [Bloodbat, firecat, etc]) to have to rank their pet through hundreds of points and get a lame boost; Compared to a good pet where you rank it too teen and it gives you spritely. I think that the higher the pedigree, the harder it should be to rank up. Or if you could reduce pet energy cost, that would be great!
