Eh, multishot amas pale in comparison with a tricked out poison necro, or a decent dual element sorceress (orb/lit for example)
Aren't you the guy who always tells everyone that dual elemental sorcs are not effective in 1.10?
I do somewhat agree with you, Orb/Light or Orb/Meteor work really well. Orb being the key because it does alot of damage and doesn't need its synergies maxed to start kickin butt. It can allow you to spend those points one of the other elemental trees and synergies.
I don't know about "pale in comparison" though. I challenge any zon or poison necro to clear lvl1 and 2 of the Pit faster than my zon can.
