Yeah, my idea would either require
- months more of design/modeling time
- making every rare coloration super generic and uninteresting (smack the same texture onto everything or just put a random little marking on its face)
- gamefreak to actually give a shit and innovate
I just always thought the Breeder trainer type was cool but pointless because they're like "oh look at the lustrous shine on my igglybuff's fur" and I'm like ?? it looks exactly the same as everyone else's but okay dude.
Also the Glaceon/Leafeon thing is so annoying because they only evolve in a certain area, so it's very likely that either you'll only get one much later in the game or you'll not have the appropriate area in the game at all.
