And totally ruin the DLC.
It wasn't broken why did someone have to do this
It is about choices.
If you cant deal with that play something else don't ruin it.
Well, I can't speak for the others, but can tell you why *I* am going to use that mod. Because the game was already broken for me. No matter what choices I make in my head or in the dialogues, I CAN'T place raider banners.
I can go TGM and place one, but it actually disappears after I leave the cell, and breaks both the settlement AND the Home Sweet Home arc past that point.
That's of course, just one of many reasons to use or not use a mod, but it will serve to illustrate a point: if for you everything's all perfect as it is, good for you, but don't assume that you're the platinum standard of gamers, roles played, and bugs encountered or not. Other people are, well, other people. On other computers. And with other mod mixes which may or may not make a difference already.
Just download what you like or need need, don't download what you don't, and don't sweat it if other people download different things. Life is too short to worry about how someone else plays a single player game, and why they don't play it exactly like you do.
