That's the cool thing about games that are designed for mods, options are limitless, and you don't necessarily have to wait for the developers to change everything you want. I've already made a few twinks of my own in my own mod, that I enjoy. and I use quite a few others made by other modders that are amazingly well put together. lots of them are simply QoL mods that don't break the game.
Most of us don't spend our free time creating mods to fix the game. You could say the same thing to anyone who suggests anything in the forum - go fix it yourself. That's just pointless. If we think the game needs a tweak in weight limits, there's nothing wrong in pointing it out to the developer.
I personally like the weight limitations.... However, I do have to admit that I like Str and melee builds, so carry weight is never an issue with me.
Of course you don't mind the weight limits because you always have a Str build in your party

Try playing without one. That's like saying "I don't have any issues with DOS2, but then again I've never played it..."
In the screen below my Str build (only lvl 17) carries more than the other 3 can, and this is right after selling all the junk. So, if instead of him I had another one that carries 100, I'd be carrying a fraction of what I can now. Most other games require a Str build because it's required in combat. In DOS2 combat dosn't require it because you dont need a tank anymore, but because of the weight limits I have to have Str. That is a stupid incentive to keep a Str build in the party. And guess what - this is just another reason I don't feel like doing a 2nd play through, cuz I can't have a more diverse party.
Kalrakh, enough with your class nonsense, both games can do the same. Please stay on topic or post some place else.
