PvP: Concentration vs. Whirlwind I'm planning to make a PvP barb. I'm either going to go concentration or whilrwind, but my question is, which one would be better? Here's my setup: Doombringer with Shael Stormshield (hopefully) Arkaine's valor or shaftstop Lavagout gauntlets Highlord's wrath Gorerider's Arreats String of Ears Raven Frost Dual leech ring ??? Str: enough for gear Dex: enough for max block Life: rest Energy: none I'm trying to get some more faster r/w charms and life charms. If whirlwind: Max Whirlwind Max sword mastery Max Battle orders 5 in natural resistance 5 in increased speed Rest in pre-req If concentration: Max concentration Max battle orders Max shout or max sword mastery 5 in natural resistance 5 in increased speed Rest in pre-req and shout/sword mastery. My main question is which build is better? And if concentration, is maxing shout or sword mastery better? And do I need a lot of faster run/walk? I imagine I would to catch zons and non-enigma necros. And what would be a good strategy to face non-enigma necros if I decide to go the concentration route? They would bone prison me and I'd be a sitting duck. I'm pretty sure I could whirl through bone prison if I used whirlwind.
