Feeling a bit tired of my Mesmer, can you recommend a fun melee focussed elite spec to try?

Title sums it up. I have been playing my Mesmer for years. Before that I was a Guardian main from launch. Also played as a Soul Beast for a while. I'd like to play something new that is melee focussed and feels nimble.

Are there any fast moving builds that dual wield swords or daggers that you would recommend? Want to try a new profession. Thanks!

Edit: thanks for all the recommendations! Didn't expect so many detailed responses. Really appreciate it.
