Diablo III: Reaper of Souls

Does it have any potential at all to be good?

It might be okay for mid-Torments but it relies on two pieces of Legacy gear. I have a Stone of Jordan and Uhkapian Serpent with -3 each, and the 4pc's -2 make it 0cd. It would be a free 1400% spell (over 4 seconds) at that point with choice of rune. They prevent monsters from walking through them, but pets can attack past it. You can have permanent Taunt, summon 25% weapon damage minions (these are pets???), or knockback (which is probably not good if there is limited range for the 6pc). If it got boosted by Tasker and Theo, that'd be pretty intense, but I doubt they're considered pets. I can loan you the pieces to try out if you want since you have Tasker to test too.
