100k dps and 1m toughness and I'm soloing T1 right now with my Barbarian. It's fun, but enemies take forever to kill. --- I asked God for a bike, but I know God doesn't work that way. So I stole a bike and asked for forgiveness.
For crusader I'm 650k sheet dps, 13m toughness - but I'm using schaefer's hammer which is additional 200% aoe damage every second around me, so my dps is probably a lot higher(also got 15% lightning dmg on bracer thats not seen on dmg sheet).
I'm farming T2 really comfortably... walk around and trash mobs melt in 2-3 seconds. I can farm T3 too but it's 2x/3x as slow and if an elite has weird affixes with walling it becomes a really hard fight.
I'd say 300k dps with 7m toughness was when I could efficiently farm T1. Like actually farm, not just sit and wait on cooldowns or kite for ages.
My Barb has roughly 380k damage and 5m toughness right now. T1 is pretty challenging for me though. If I ever have more than 1 group of elites to handle I often die. --- 3DS FC: 4210-5054-7114 - Pokemon X / Y IGN: Dylan / Lemons
Wizard - Over 500K DPS and 2.2m toughness unbuffed. However T1 is not even a challenge for me because after buffs plus stacking over 30% meteor damage plus lightning damage I deal 7-8m damage per meteor.
Sheet DPS is only scratching the surface, eDPS is the true indicator. Just sucks there's no good calculator for eDPS atm until D3UP updates to RoS. --- I pretend to leave and then......SURPRISE ATTACK!!!!
