I still have to get out to buy and sell, for the charisma buffs. Armor paint is barely a drop in the bucket compared to a complete charisma outfit.
I diddled with Charisma clothing when I first started playing, but stopped after I found myself in combat a couple of times in a formal suit. It didn't help that it felt ridiculous getting undressed in front of shop keepers to impress them.
On the other hand, wearing charisma clothing while in power armor kind of bypasses that. There's no fear of forgetting to change into combat gear, there's no penalty (or benefit) to wearing anything in particular under the power armor, and stepping out of power armor to bargain feels as reasonable as holstering your normally always-drawn pistol.
I'm not a big fan of how early Fallout 4 gives you power armor. The
logical way to play is to use it continuously pretty much from the start of the game, which renders everything about normal armor pointless. I
like fussing with normal armor and tweaking its upgrades and buffs, but it's really inferior to power armor for everything but stealth, and power armor doesn't seem to be a big penalty to stealth anyway.
Theoretically, fusion cores should hold you back, but in my second playthrough I tried using it from the start to see if I'd run out, and I pretty much never did. There are lots of them around.
Survival might change that in both directions. It's a big incentive to use power armor whether you want to or not, where I found pre-1.5 that I could do everything but The Glowing Sea without it. However, Fast Travel is a tremendous crutch if you're wearing power armor, because it doesn't use Fusion Cores. With no fast travel you're going to use up Fusion Cores much faster unless you deliberately walk, and that's incredibly tedious.
With that in mind, maybe I'll give the new Survival Mode another shot. I got as far as my initial settlement of Sanctuary, but stopped because I was really put off by how low the new carry limit was. Normally, by level 30 or so I have trouble keeping my loadout below 200 pounds, and I couldn't see playing with a carry limit of 115.
200 pounds of course is ridiculous in real life, but I'm also aware that Fallout's weights are generally silly. Higher level weapons weigh 2x-3x what real rifles weigh, as does combat armor. The other thing I'm tempted to do is look around for a mod that changes weights to something reasonable to go along with the more-reasonable carry weight limits of Survival Mode.
