Here's some more food for thought, the split does exist.
Krookodile, design wise, might've been an unnecessary evolution. Either fix that nose of his or give his base stats to Krokorok, who is way more appealing than it.
I think Electabuzz was pretty cool and didn't need an evolution.
Rhydon was badass.
I think un-needed evolutions were the likes of Tangrowth, Politoed, Slowking Gallade.
And why does Snivy de-evolve? it starts off with arms and legs and ends up paraplegic, i mean come on?
I feel oddly about Duosion to Reuniclus. Only because I hoped the Sp Attack would spike, but only it's HP rose......
