I suppose it make sense, having in mind that ampharos came from a family of sheeps (and ampharos is said to be based on a sheep as well, don't ask me what kind), but its mega form its just... Too FLUFFY.
Oh, I see. I believe that all the pokemon chosen in general were pretty random. I mean blaziken is cool, but why it out all the starters? Maybe it was just the favourite of the designers along with the others. Because I don't think that EVERY SINGLE evolved form will have a mega. I mean... That's a lot. Anyway, the thing is that we agree that they could made it better in ampharos
