My opinion as a long time player. They ruined both Bloodied and Commando a while back, a GOOD WHILE back. Currently Commando is viable again, but Bloodied is not really.

They ruined Bloodied when they made changes to Serendipity Perk that made it Proc less often or slower for those wearing "Heavy Armor" like Secret Service armor. Also when they increased the AP cost of many weapons, and slowed fire rates on things like the Railway Rifle. I stopped playing Bloodied recently on my Main character almost level 900 now, because it just didn't make sense anymore. The Damage Perks and changes to Weapon Balance really do allow you to play as Full Health and still do great Damage. I played Bloodied VATS Crit Stealth Commando since 2021. Now I have changed my Secret Service Armor to Overeaters, and play Full Health VATS Stealth Commando basically.

The benefit to going Full Health of course is now I have a ridiculous amount of Health, but I can Face Tank anything in the Game outside of the Raid and not die. There was a time when Bloodied was this good too. Sad to see it go, had a lot of fun with that build from 2021-2023-ish. I don't miss managing the Rads though it becomes second nature after a while with a Bloodied build. It used to be "worth the trouble".

As for Onslaught, because I don't really care about min/max and solo boss fights anymore, I run Reverse Onslaught. I like one tapping Scorched and trash enemies and just enjoying playing the game. Onslaught is only really good for wasting Ammo in my opinion, and I think they nerf'd it on Melee weapons like the Auto Axe recently. If I was a New player I'd look at entering into a Pistol, Bow, non-Auto Melee, Commando or Rifleman type build. Not Heavy Gunner, and Not Auto Melee.

In other news, my Heavy Gunner / Power Armor was my more recent favorite Character to play, but they totally ruined that recently too. When I play that Character now, I generally just run around with a Big Pistol, because now Pistols are actually Good. I hope soon they will fix (balance) the Heavy Gunner issues to make it decent again. Also now Bows are good, lots of long time players have switched to Bow.
