This is an interesting topic.
Like most people, I’ve got a few characters I’m not excited about. Some I don’t recognize at all and don’t agree with the notion that they’re icons, some I feel are better suited to an assist role for various reasons, and some because they’re competition for the ones I do want.
But I can’t say that there’s anyone I’d rather not have in the game at all. Pretty well all of my least wanted would make me happy to see as assists.
Also, a lot is highly dependant on whether my wanted characters get in. While I have some characters who are competition for a different choice, I have no problem with the other choice and my favorite both being in. It would just annoy me if the other was chosen and my favorite was left to rot. And then there’s my shoot-for-the-moon Dovahkiin, after which I could just stop caring about anything.
Still, with Squirtle returning, I’m the most hyped I’ve been for a Smash game and nothing can kill that completely for me.
