95% of the time i play this game i join a room or some joins my room that has modded weapons and shields. Which pretty much makes the invincible and can one shot any of the hardest bosses. Next is duping, any rare weapon that is found is duped a million times and of course you can dupe money. Thus, the game could be great because you'd feel proud to work hard and get a rare weapon but that is nullified by the fact that anyone can get it by duping or even have a mod-god weapon.
Why haven't they learned the lessons from Borderlands 1 and put a stop to this? I would like this game much more if they would put some safe guards in it to prevent this type of exploitation. Any and every MMO has systems to prevent mass production of a signal item or even modded weapons. This kind of thing is so prehistoric with such simple solutions and i'm bewildered that it still exists at all.
