Ok, bros. Since yesterday I've been toying around TW2 XML files to see how much I can rebalance the game. This is the result of my endeavour:
RebalanceTW2.7z - 28.9 Kb
To be frank I build this modification upon:
Better Combat Mod
CEO - Complete Equipment Overhaul
I simply saw no reason to do the job someone else had already done.
The modification encompasses all the fixes from these two mods plus the following:
Various modifications to player's initial parametres including lower damage output, hp, hp and vigour regen etc. Now fighting against common soldiers/monsters should prove more challenging, especially farther into the game. Tip: try striking them from behind for extra damage.
Weaker huge boss monsters: draug and the dragon. This is because the CEO mod lowers parametres of your weapons and armour.
Significantly. However, it does not nothing to change the hp and damage resistance of those creatures. As a result the fights with them drag forever, not to mention are uber-difficult and annoying. I lowered the bosses' resistances and hp as well toned a bit their attacks. Now, in spite of you having worse weapons and lower armour class the monsters should be manageable. I checked it myself. You can win those fights with some healthy struggle if you know what you are doing. Played on Hard.
Nerfed Quen. Quen works as before. However, even in its highest form it can withstand one attack only. After that it dissipiates and you have to cast a new shield. I also lowered the damage its shockwaves produce upon you getting hit. Add to this lowered vigour regeneration in combat and I think I limited its impact on the bettlefield albeit not usefulness - I still found myself casting it more often than any other sign.
Installation:
Just put all the folders (abilities, items and globals) from the archive into CookedPC folder of your TW2 installation.
For the sake of making myself clear so that dumbfucks can understand me it should look like this:
G:\Program Files (x86)\GOG.com\The Witcher 2\CookedPC\abilities
G:\Program Files (x86)\GOG.com\The Witcher 2\CookedPC\globals
G:\Program Files (x86)\GOG.com\The Witcher 2\CookedPC\items
The files placed there will take priority over default ones.
Known issues:
The bosses hp fix will take its full effect only if you load the save in which the monsters haven't been loaded onto the map. This means, you must reload the game from the save before they appear in the location e.g. before entering cursed battlefield or before the events at the summit in act 3 (not, not later. If the dragon already flies on the map when you load the save it will be 'bugged'). Else, the monsters will have their original hp,(but curiously not damage reduction). There's nothing like fighting 2000hp dragon when you can deal max 60hp of damage with your meagre strong attack.
The CEO mod changes a lot in the items including the slots for armour enhancemets and runes. This unfortunately means that any runes/enhancements you used up previously will likely disappear. No fix for that, bros.
Anyone knows how to get to hardcoded stuff? I really would like to change, for instance - the way Quen works e.g. make it so it blocks a fraction of damage, not 100%. I am
too stupid not tech savvy enough to get there, unfortunately
I would appreciate you feedback, and requests. Tell me what should be done to make fighting more difficult without resorting to cheese.
Disclaimer: As you can see I merely added a few minor things from myself and tried to rebalance the boss battles a bit. Most of the work was done by Lautreamont and Kindo, the authors of 'Better Combat' and 'CEO - Complete Equipment Overhaul' mods respectively. Obviously, most of the credit should go to them.

Tormentttt~!!!
