How about a non-support ranged dps?

[Shurrikhan]

Which class would you prefer to have a whip?

The AoE class. I mean, honestly, you give a job a whip and make it centered on itself or its weapon characteristics, rather than on a pet, and what else is it going to be? You walk in, whip in hand, and proceed to auto-attack 4 enemies at a time. "Hi. I'm AoE."

I believe it was called Flayer in the 1.x localization notes though.
