There should a character switch button? come on nexon! Listen to the players!

Well... You're gonna have to log off to switch into characters on multiple accounts. I feel like having two separate accounts is safer, and also more space efficient. (I'm assuming you're talking about mules here)

I agree with this.

Since Nexon bans so many people for absolutely no reason at all, and for completely retarded reasons as well, you would be better off not having more than one char per account.
