I was looking for a way to utilize the new ability at level 4 master warp blade. It turns out that it works pretty well with Shadow assault. Pretty concept behind this build. Right click and win. Block and stone skin are not mandatory but will be very helpful to survive once you open up on someone. This is more of an all-in build to kill someone like a chogall or lt morales. It's a very fun build if the enemy team doesn't have too many stuns. Searing attacks can also be taken at level 7 over follow through, but I find myself out of mana very often, so I wouldn't recommend it. Plus, it helps to gain more damage lost from not taking gathering power that doesn't require a cooldown or mana. At level 20, nerazim frenzy can be taken instead of nexus blades if you need a little more healing. In the early game, you will still have the same power as before. But you will have more power in late game to take down anyone who is not in a group. The goal is to get a kill and get out. Try it out, you may be surprised at how effective it is. It's a much more aggressive play style so you have to jump in at the perfect time and not come out until you have one or two kills.
Good Luck!
