What are champs that Riot intended for one role but ended up on a completely different one at release?

10 years I've been playing and I don't remember much of that happening. Was Taliyah intended for mid or jg a the time? I'm pretty sure Riot talked about Sylas being a jungler but he ended up in the midlane. I may be MandelaEffect-ing myself.

It's nice to learn some LoL history.
