Possibly. Just a did a solo butcher run...30 minutes, not as much gold as it use to be. Stacked NV5, gotten maybe 4-6 yellows, all junk. Let me try A2 solo now and see how that goes.
A2 Inferno is doable solo now. But some Elite packs can still be a problem depending on how they're thrown at me. Ice + Chain + Arcane Laser and my goose is cooked.
Stats:
HP: ~32k
DPS: ~13k (think it went up after ASI nerf today, weird)
All Resist: 700-800
