When you post a spec for discussion, we'd like you to have some evidence or testing that indicates why it might be good. Note that providing such in this case is patently impossible, as we have no idea as to the details of a number of the talent changes. And even if we did, discussing the balance of builds without knowing all the changes seems unproductive at best.
The cycle would be 1s/5r/5n, Dp/Ip, slow MH mace fast OH dagger.
It seems to me that picking up the two +haste talents would greatly increase the scaling of poisons and even with the +damage bonus killing spree doesn't seem like a major talent to lose, and Prey on the Weak has always seemed lackluster due to the requirement of having more hp than the boss. Additionally, and this is speculation, with a nebulous unannounced change to haste scaling (that would make it a better stat for all melee) having two talents that increase your melee haste would increase the scaling of haste further, making the spec even better.
