Class/Race combo you would be most impressed to see at max level?

[Ladylag]

So I'm a big noob, never been anywhere near the level cap. I had this conversation.

Wife: "Hey my friend plays on project 1999!"
Me: "Really? Wow! What is his character?"
Her: "Level 50 ranger."
Me: "Holy shit that's so hardcore that's the hardest class to level I think!"

Then I was like, wait what is the HARDEST possible class/race combo to get to 50? Like, gnome paladin or something? What could you see running around at max level that would make you flip your lid?
