I'm going be playing a melee wizard partner up mostly with a DH.
I can pretty much finish the build before I get out of normal (around level 30), and I won't be using shield because the bonus armor wouldn't be that useful and is just mostly focus on keeping the entire map snared for melee and sticking a Slow Time for all the range attacks. Critical Mass is just to reduce the cooldown on Time Warp.
For boss fights, I will be probably using something like this, which I can still finish the build relatively early, and probably will put on a shield.
What do you guys think? My usual play style is not big numbers and is more focused on control, and the more annoying I can be the more fun I think the builds are.
