I went hipster sword dual wield cleave build and its really quite viable now that duelist has the gladiator class. Basically gives you a hefty bonus to dual weild block as well as converting 100% of the block chance to spell block. Best part is that you have A LOT of attack speed, meaning you basically fly accros the map with whirling blades.
Another great boon that makes the build more viable is the blasphemy gem. You dont have to put any points into life steal nor do you have to run a life steal/life on hit gem, you dont have to put much points into accuracy either, you dont have to worry much about mana and your frenzy charge generation is solved. Everything with just running poachers mark as an aura. I run haste and poachers mark which speeds up whirling blades even more. Clear speed isnt top of the top but its quite fast.
+ more flask charges from poachers mark means i spam onslaught, crit and evasion pots all the time. Pretty nice
