Actually you can blame microsoft for duping, with the ability to put characters on USB there is nothing stopping anyone from making copies of their profiles and just sharing whatever gear they want.
The real evil is modding because billion damage guns/billion level characters/billion badass rank for waaaaay off the chart stats, again blame microsoft for that by making a HDD that could be read by your average computer and the ability to transfer your gamesaves off to USB. Hex modding and programs like willowtree and modio for the casual modders are what you really hate, not duping trust me. --- I don't always browse Gamefaqs but when I do I prefer to keep urban dictionary open and in another tab
This is a classic case of fixing something that wasn't broken. The loot drop rate in BL1 was excellent. Gearbox f***ed it up by making drops significantly more rare in BL2. People don't enjoy having to farm a boss for six hours before it finally drops a legendary. People also don't like the fact that chest runs are useless, since about 98% of the time, chests don't have decent items. People also don't like going on vending machine runs, since vending machines are just about as pointless as chests. They never have good items.
So instead of being angry at what other people are doing, point your blame to Gearbox. They made all these changes simply to make everything extremely inconvenient (in an obvious attempt to make the game feel more difficult), and they failed miserably.
First off you say "people don't" alot but what you main is you don't like. and you really can't fix duping in any game, if people want to do it they will just like in fable 3. as for the farming 6+ hour try playing FF11. then and only then can you complain about the drop rate. the idea was to get people to trade with other people, making new friends and not being so anti social.
This is nothing like ff11 at Least there u could up the drop rate with a thf and had to wait 21-24 hrs between kills
its time you go back to the game and break down the mathematics of it. yes you can up the drop rate a little with thf. can thf solo any and everything? no is everyone a thf? no. so lets say you have a drop rate base of 10% ok now add the thf with all drop rate adds. it dose not add to that 10% base thou. O'on what it dose is roll more die to try for that 10%, is if 10% is to a 6 on a die and you need that 6 to get the item you still only have 10% chance just extra roll. and in bl 1 & 2. you have the more plays the better the drop rate. so add 4 ppl and you have a bl thf. and not all mobs had that great a pop time very few in fact. some pop windows took 4 days after being killed and then could take up to 24 hours to pop the mob its self.
Do you really type like a six year old or are you just joking around?
Anyways, I don't mind duping. The whole point of this topic is that people dupe because the drop rates are too low. Plain and simple. --- http://i.imgur.com/EFYRV.gif
