One shots
There is a huge problem with these in the game. Even when you're pumping a lot of points into Vitality, assuming you're doing an Elite playthrough of the game with no particular farming (so no farming Grell's Eyes), there is always that monster in Act 3 who will one shoot you no matter what.
Assuming you're melee, if you're lucky it gets blocked or reflected. If you're not, you're just dead, and there is absolutely nothing you could have done. It's complete RnG. And that really sucks.
You could scale down the damage graph - but it's very hard to scale it down properly. It needs a lot of playthroughs to get the right balance.
I think a nice alternate way would be to just double the amount of HP the character has. So basically, double the base HP, and also double the HP per level and vitality point.
It would solve the one-shotting problem without making you completely OP - you still receive the same amount of damage, and you still have the same amount of healing to do. But it gives you more bufferization.
I think the glass cannons would still get one shotted.. But there's nothing much to do about it :p
However, the Berzerker skills giving back a % of the health pool would have to be divided by two (so that it gets the same healing as before). Otherwise, the Berzerker class would become even more powerful than it already is
Maybe the health potions would also have to be toned down - this would need some testing (with this change, their effect would be slightly more effective, since you would have more health to heal).
The one time I played Berserker through Veteran NG0, I started using a shield in the Forest level. It felt bad. But I didn't know what else to do. Right now, "everything is OP so nothing is", but fixing that would require a ton of nerfs to (almost) everything (except health and armor, and maybe HP regen gear and gems). My mod pack thingy addresses a lot of issues, but the damage graphs probably haven't been nerfed hard enough. The player gives up some OP sustain and protection skills, but the nerfs to enemy damage are outscaled by level 30 or 40 or so, even with a nerf that I currently include. It's a headache.

Yes - that's what i was talking about when stating that it's very hard to scale down the damage graph. You need to do a lot of iterations and fine tuning before you're at the right spot where the damage does not outscale you, but you are not OP neither.
