You are basically saying game devs' balance patches are useless for single player games, and that op stuff should be kept, they went through that entire EA process to balance/nerf OP things, just that sadly lone wolf wasn't in the EA.
If a single lone wolf character is stronger than a party of 4, then there are issues, because why bother use the companions, they spent a lot of effort writing the stories for each of the companions and interactions between companions.
Lone wolf experience is meant to be played with 2 characters, not one, so if you find encounters hard then it's normal, I don't understand why you want the the game to be easy for yourself only, if you want that you can always tune down the game difficulty.
So yea, I'm looking forward to a nerf, if they actually have one planned.
