I do the same for Blitz.. Terra's staff and as little gear as possible to enhance its MACC. I also like to try and announce to the group when I am doing it so I don't have stun proc while they are trying their own triggers.

IMO, the 1000 needle fix is easy.. make it work like EVERY OTHER NUKE IN THE GAME. Have the resists work in 1/2, 1/4, 1/8 ect. increments and not "all or nothing" like it is now. As for a workable Blitz fix.. not so sure there. I don't know how hard it would be to reverse the order of events in casting the spell to make the damage happen first, and then the stun. That way it can still proc. I am no programmer, though, so as simple as that sounds, it could be a monumental task.
