Just rebought D2 and the expansion (the battlechest)

[Nori]

I'm pretty sure D2 multiplayer uses a dedicated server to save your character and items. It's not on your hdd, so all you have to do is reinstall the game and sign in to your b.net account.

Assassins are currently the strongest characters. I've got a friend whose trap assassin can solo the Nightmare bosses in Hell difficulty. That's insane.

My personal favorite is the barbarian. Once I get the Immortal King body armor I'll have the whole set.
Whirly Barb + IK = ;]

I know a summon necromancer and hammer paladin that can do the same thing.
