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.
I've been using an old MF Strafe/Multi Zon from 1.09 and she rocks through the pit no problem. My speed is only really limited to how fast I can check the drops and walk thru the pit. There may be better chars out there but the Multi Zon does work well. The 2nd level is really easy, you can damn near kill everything from where you enter the level.
