Not lot of players like adventure, and when quest need they only doing something what bad for other players or literally nothing. So making adventure for guys who really like and enjoying, filling up with shooting target or get team with 2 new makes people frustrating. Adventure really team work needed game, one wrong step and everything lost, you need really good skills and high level team members to win, and also not forget who really investigated lot of for adventure (winning event, wright brothers or getting high lvl gun) can be everytime in opposite team. At hungarian market, about 30 player like play adventure (about half are hothead, swearing when someone make mistake, not like low lvl guys in his team, etc), others who tried sometimes for quest really not enjoying because you need to everything precise, no chance to learn it, because they not have got enough patience for accepting negative words. So if adventure going to be more enjoyable (and not one misstep make everything gone wrong, I hope one day they make duel mode too, 1 vs 1 or 2 vs 2 or team fighting against team, new maps, etc), we can talk about putting back adventure winning requirement.
roy o benonn viewpoint only, he want other get it slower, because he paid for something what is better than other thing, we need accept that viewpoint too. But we don't know what InnoGames plan about dmg things, making upgradeable weapons with 1,1 and not upgradeable ones 1,2 (like lincoln and golden colt), so giving something to F2P guys have chance at duels not bad idea, maybe some will do it more times (need more opponent for high duel lvl guys, do something about that too, thanks), but you can still use your weapons what have about same dmg but with better bonus (like hooker and david has got nice bonus and lonesome too), still you can win duels.
I'm hope golden colt not will change, but if really need to change dmg part of gun, make little lower starting dmg, but not change +1,2 dmg per lvl one. But if make it lower too much, again, golden gun set will become obsoleted one, so new quest for that and other ones will be less interested.
