I only have 800k or so Gold, and I think I need to upgrade my gear differently, or just a little more. I can't get much, obviously, but it might help.
I'm using Frenzy /w Sidearm and Revenge to heal me and as a damage dealer when it procs. I use no Fury except for Battle Rage /w Marauder's Rage. I'm using Leap /w Death From Above for the stun, and Threatening Shout /w Falter for the DMG and AS reduction it gives. I keep War Cry /w Impunity up at all times with Battle Rage.
So basically, just Leap in, Frenzy them, use Revenge when it procs, and use Leap and Threatening Shout basically as often as possible.
Since I don't have a lot of money for good gear, where is the best place for me to farm? It'll have to be on MP1 or lower. I haven't tried 2 yet, but honestly, I probably couldn't handle it. A lot of Uber/Champ/Elite packs (I forget what they are usually called in D3), gave me some trouble towards the end of Act 3 and Act 4 on MP 0.
