This is not just for a continuous stun, all though would piss off some people. It is really a great way to block people off from being able to leave or enter areas. If you catch a few people in it that is great too. I have noticed with most players, they see a wall they run into it and soon as it goes down CHARGE! In this build, charge = well ****.

Tassadar would also work well with this line up.
Jaina could also replace Nazeebo if more damage is needed.

The main map that I think this would work well on is Cursed because of the tight spaces and the time needed to capture the tribute. Infernal may be good but I don't know if there is enough AOE to be successful.
