Well, that's because you're level 66. You aren't going to find any more encounters that will kick your ass at that level.
Are you on PC? There are a number of mods to increase difficulty. One the most interesting one of those is More Spawns which increases the number of enemies and not so much their levels. Can create some pretty rough battles. It also makes for some fairly epic moments. There are lite, medium, heavy, and some odd ball versions. http://www.nexusmods.com/fallout4/mods/4253/?
How does your weapon setup look like? if you use an gaus with double damage on enemies with full health and an bleeding minigun the game will become easy as they weapons is so powerful.
Try starting over and playing DiD (Dead is Dead).
Add realistic (whatever that means to you) RP elements.
Examples:
1. Carry only one Long Gun and one Side Arm. Who can carry a whole arsenal?
2. Limit the amount of stuff you carry to your own personal carry weight in real life. 50 lbs or so, that includes armor.
3. RP that fusion cores are dangerous to you when they are naked. You can only carry 1. Either installed in your P.A. or in your Lead box that weighs 10 lbs. that way when you are out in your power armor and the F.C. runs out, you have to leave it there, go home and get another one in your 10 lb lead box and bring it back to wherever you left your P.A. You won't be using P.A. as much!
4. No drugs. You are a responsible advlt, not some strung-out junkie.
5. Heavy weapons can only be operated while wearing power armor. You aren't Jessie Ventura in Predator.
5a. This includes Gauss and Assault Rifles. The A.R.'s in FO4 are water cooled machine guns from WWI that were only mounted weapons. The Gauss is the size of a small transmission.
6. If you take a H.W. and wear P.A. you cant carry any other weapons. Both hands are on the heavy.
7. No taking healing items during combat. You are too busy... with combat.
8. No legendary items. This is a combat simulator, not Harry Potter. No magical items allowed.
Or whatever else you might invent. Others are even more creative.
Yeah. In normal mode my character started seeming OP once I got into the 30's. Then again, I did invest heavily into rifle damage and armor upgrades so, not sure there should really be anything to complain about when I did it myself.
One option is to stop playing, and wait for mods. I present that idea with absolutely no sarcasm at all. Difficulty and scarcity mods for Fallout 3 and New Vegas breathed new life into the games for me. I wish I hadn't explored most of the content prior to those mods arriving.
In particular. wait for Fallout Wanderer's Edition (FWE), Monster Mod (MMM), and item scarcity mods. Also, if Chuck Steel is still playing, hopefully he'll create an interiors mod for us. The man's work for New Vegas and Fallout 3 is stellar.
Personally, I expect to continue playing, but I'm trying different builds and learning the map. I don't limit myself, but I have personal goals like:
.
1. Learning the map, to create kind of an optimal future run to scoop up collectibles at low level.
2. Try a thief / minimal killing character, that just goes around stealing stuff.
3. Play an OCD character, who collects comics (without hints or guides).
4. Build a few save games, both male and female, with starter characters of different types, with Red Rocket built up and aready for action.
In preparation for the GECK, I'm also combining several existing mods into one single mod, to manage my future mod load. So far I've created one mod that includes the content of 5-6 others, and it's working flawlessly.
Of course, our overarching goals may be different. I'm planning upwards of 1,000 hours in this game, playing and modding, just like I did for the previous titles.
Enjoy.
Try limiting yourself to "lowly level" weapons.
I am level 60 playing on Survival mode and I use the following non-legendary weapons.
#1 - 10mm auto pistol (39 damage)
#2 - .38 auto pipe rifle (28 damage)
#3 - .45 night vision sniper rifle (35 damage)
#4 - .308 recon sniper rifle (92 damage)
I wear non-legendary light combat armor.
That is usually how it goes. First few levels will be death on wheels, until your skills start to adapt, new strategies develop, and your gear/perks makes things easier.
I'm in the late-20s now, got some great weapons but weak armour. Combat shotgun makes things so much easier, but death is still a realistic threat. I can only expect that it'll get easier as my perks start to plateau and my gear further improves. But, the important thing is that I'd've earned it. Getting to that point requires surviving my butt off.
Though that gives me something to look forward to
It is funny right when someone tell us that survival is too easy, and the other one said that it bullet spongy.
Guess some people just never satisfied.

Well... you are well above the soft level cap and I am sure that you have maxed out both your weapons and armor so, of course you're OP'd. I don't know what they're max is, but it has to be around 50.
I don't consider it a gimp that I only use found armor and generally don't improve it all that much. I do improve my weapons though, and, even at lower levels, doing 77 per hit does seem a bit OP (and that's without any perks so I can only imagine what it's like perked out).
I realize we probably shouldn't have to gimp ourselves, but, that's just what I do. I do it on most of my games.
This is a common problem in games like these. This is unfortunately where you have to start nerfing yourself. Put all your perks into non-combat skills etc. It's apparently impossible to scale a game properly to be challenging in both earl, mid and late game.
Well... maybe not impossible, but I've yet to find a Beth/Zeni game that does it well. ESO does it pretty well actually, but, then again, there are no difficulty settings. It just gets harder and harder and harder the longer you play!
As well it should. Increasingly bullet sponginess is not a difficult setting, it's an annoyance.
Soft level cap? I am not sure there is one in this game.
I haven't completed any of the major questlines yet, and I am at 57 I think. Still leveling regularly. Barely touched RR and BOS. I think I mostly do MM stuff still. And build.
I did switch to Survival to increase my legendary drops, and haven't found the need to switch it back yet. I see the OP's point. But if the 80+ player posts are right, it will get harder again.
Psycho-Jet. I just experiment.
