As long as you keep upgrading your gear you will never not be able to solo, even on the hardest difficulty settings.
In fact with the best gear in the game you'll be wondering if there should be higher difficulty levels.
I don't know if this is true or not but I've heard the drop rates are higher on consoles as well. So time investment to get high end gear isn't as much as it is on pc.
Thanks I'm definitely going to keep it then.
PS4. I'd definitely hold out for it or the One version if you can. It looks and runs great.
What console are you playing on? I'm thinking of getting it for XBox 360, but I may hold out until I have a PS4. Who knows when that will be.
