Does egg rarity even matter?

[Mokona]

Aside from skills which I know about does the plus to stats even mean anything? +2 hp doesnt really sound like anything to me but if that +2 is actually +200 by the end then I would like to know

It's just a bonus to the stats like the +2 hp, your monstie will get a bit more hp than a normal. and yes the better the rarity of the egg, the better genes that it'll have. but the chances are small

From everything I heard the only thing that matters is the gene's.

The bonus stats you get upon hatching a monster are pretty much irrelevant.
From what I hear getting +2 to HP doesn't give you any more HP than that at any point..

So your max level monster will still only be +2HP more than a maxed level of the same monster that didn't get that bonus.
So it's not worth farming tons of eggs till you get a monster with the perfect hatching bonuses.
