I posted these suggestions on another thread, I think they'll fix the game for us:
1) remove all random high level loot from grain sacks (rubies, dragon skin, recipies, etc)
2) reduce random loot by 80%
3) completely remove mutagen synergies
4) nerf the more unbalanced skills (bleeding wound, bomb splitting etc)
5) nerf quen (damage bleeds through when quen is broken, if the damage is more than the quen sign intensity, stamina does not recover while quen is up)
6) completely remove recipies from random crates and sacks
7) reduce XP overall by 30%, and from main quest line by 60% (way too much XP there. Most of it's there)
That should pretty much fix the game.
I'll mod it once I figure out how to mod this game :>
Contrary to what some people say, giving enemies even more damage and health won't work. It'll just start feeling all wrong, when you plonk away at a guy for 15 minutes and barely do anything. No, that's a crappy inelegant solution. It's everything around it that needs to change. Don't make the witcher weaker, just make him have to work harder to be strong..
Right now I don't need to work at all..
Starting level quen is good enough (on death march there's little reason to upgrade it because it'll break on any attack anyway, more or less), and I pick up all I need from corposes or crates. Be it weapons and armor that suit my level, or recipies, high level ingredients, whatever. I just go and do quests and kill things without ever needing to prepare in any way
