Their game, let em play how they want. If you don't want them in your game, don't play with randoms. I know 99% of this board somehow prefers solo play anyway, so I don't know why that's a problem at all.
Well I think the problem comes from both sides. Some people who agree with modding think those that don't aren't having fun and vice versa. I spend alot of time playing legit, I just enjoy making weapons and stuff for people who are tired of farming...not everyone enjoys the farming aspect of the game and I believe that giving them weapons they've been searching for can improve their experience and extend their playtime. But I'm just a lame casual who plays games to have fun :'(
