Yes. I beat every boss my first playthrough 1 on 1. Or 1 on 2 for like the gargoyles and S&O and Four Kings. I even beat Gwyn by myself, and I had no idea you could parry him. Come at me DkSII you P***Y

Beat them at SL1 solo, solo at SL10 shieldless, solo at SL10 on NG+ and beyond, and solo on NG+7.
There are easy strategies you can follow to avoid taking any damage.
1. Ornstein's attacks are easily blockable. So block them.
2. Smough's charging hammer swings from his right to his left, use this fact to position yourself in a way that always lets you roll towards the center of the arena. Getting cornered or flanked in this fight is bad
3. You can sprint down one side to get some 1v1 time with Ornstien while smough catches up. If you can get him to charge into a pillar stump, take off running but make sure ornstien has a clear line of sight to you. If you don't bearclaw this might be difficult to track him while you run.
4. Its far easier to kill ornstein first. Super smough doesn't have any attacks that aren't easily avoidable. Don't get greedy, slash/cast a few times then get back
