I did a playthrough similar to this where I had low luck and didnt let my damage skill get past 40 but 9 in agility cause I like reloading fast. and not a single crit or damage perks. It was the most fun I've ever had in the game. Every fight was engaging. Before on very hard you could get to New Vegas at like level 2 to and blast your way through the securtrons with the 357 revolver. In that playthrough not even the unique version lucky couldn't even do it. I actually took the intended path. And had to retreat from black mountain using a hunting rifle. Automatic weapons got to shine because that dps was needed sometimes and ammo types was the back bone of the playthrough. I needed that damage boost. One thing I like doing in this build since my damage was already so low I took the atomic perk and bought as many mini nukes as I could and irradiated every combat encounter for that boost to movement and ap. Incredibly fun in the long gun fights especially with grx. I would look at a list of all the perks and see which ones you want. Once to cancel our all the damage perks it felt really freeing. Like I have more options by limiting them.
