Say you have end game gear. For fire sorc, you have phoenix. For blizz sorc you have 35% fathom. For lightning sorc say you have griffons and crescent moon. What's the best mf sorc for players 8? Is it still lightning sorceress? Also assume you have infinity and sunder charms.

I think enigma is a key piece for mf. Gheed's fortune charm.

The question isnt what is good end game gear, the question is, given that you have access to any end game gear, what sorceress build is best for players 8?

I am only talking about D2LoD ... so it is Light Sorc with infinity merc so that you kill faster and remove a ton of Lightning Immunes. Marrowwalk so you can cast Life tap on monsters that remain Immune Light, and it works on skeles if I remember correctly for your merc to stay alive leeching.
