S&B Duelist Help for 2.0?

Planning to run a S&B Duelist for Warbands. Is this good enough... I don't think I won't need Jewels too much and I do plan on playing this character past the League and into Standard. Will this character survive and handle well even up to Merciless and Maps?

Planned Gear Linking

Double Strike
Multistrike
Melee Splash
Life Gain on Hit
**Faster Attacks
**Reduced Mana


Other Gems Unsorted but plan to socket in:

Riposte
Reckoning
*** I'm not sure if they will both proc properly...


Flicker Strike (Mobility + Gap
Whirling Blades
Leap Slam (For Cliff Jumping)
Haste

Any suggestions as to what else I should look out for?
