I have always wanted a burnzilla for my fire and an earthwalker for my life and so on. I have these pets, but they still have the default stats. I have epic pets with great stats, but they are ruby shenglong dragons and pets that aren't that cool or give cool spells. This idea woudn't defeat the use of hatching because you'd still need to have already hatched a good pet that has good stats and already have the other pet too. You'd probably need both pets to be adult. This would eliminate useless hatching to try to get all the stats you already have on one pet you want. I think it would be beneficial to wizards that have their greats stats and pets they don't desire.
