Well, I've already started helpin'out ages ago. I only like hatch like once or twice a month. xD
I suppose it wouldn't hurt people to stop hatchin' if they aren't really aiming for a speicific colour. So maybe we should just encourage this? xD
Anyways, buying underpriced pets is kinda pointless. I mean if you buy them because their underpriced, people will just sell more underpriced pets expecting you'd buy them. Really, it's just encouraging people. So I'd just say if it's worth an extremely cheap price it belongs in the forest. If you think it's a completely and utterly, quintessentially hopeless (guess which movie I got that from? xD) pet which needs a horridly low price in order to sell, just throw the pitiful thing in the forest! Y'know, increasing it's price isn't really going to do any justice to the poor thing. I'd also like to say, if you can't think of a reasonable name to go an a hatch for a reasonable price, just don't hatch the pet and throw the nameless thing in the forest. Saves everyone trouble in my opinion; no upgrading your shop to support pointless pets, no economists with headaches.
Oh yeah, something else I'd like to say. I'm not sure if anyone's going to agree with me but, could we have some people just try and hatch seasonals less? I mean even the facy coloured ones have pretty worthless prices. I'd also like to tell some of them psychos who could find like 30 eggs seasonal eggs a day to kinda tone down their rabbid searchings. Increasing the rarity of seasonals isn't really going to help by the way, some people only find 5 or so because they have lives outside the internet xD
