It ruins the iconic look of the pokémon. They don't have defined appearances anymore. Before the last few generations, aesthetic variations were what made that pokémon unique and interesting. Nowadays, tons of pokémon have that shit, so it completely kills the novelty of the pokémon being unique for its alternate look. It's trying too hard to make them all cool or whatever, which I conversely see as them shitting all over what Pokémon once was. Each generation they get further from that with their increasingly shitty pokémon designs. That's why this every-other-poke-has-alternate-forms bullshit, along with everything else that craps on its origins, is slowly driving the series into the ground, "for me." I used to love the pokémon and learn every single one of their names. For the past 2 or 3 generations, there have been quite a few of them whose names I never learned, and, as you can see from my previous post, was also completely unaware of their alternate forms. Every time I turn around, there's another fuckin' poke with shittons of different variations. If it weren't for that event recently, I don't know when I would have realized that there were shitloads of Vivillion forms (or more than 1, for that matter). Also, I probably wouldn't have learned that shit's name, either.
