SOEs con system is ill concieved and messed up, but thats because they try to meld solo and group gameplay together seamlessly when in the beginning they should have shoved all the hardcore doodz on 2 servers where every mob is heroic and most every boss is a epic X2 but SOE isnt that smart. The other problem is what people think should be and its really stupid for some people to say single heroics should be balanced for a group, that is the dumbest thing i ever heard. If duos are both level 25, and a heroic mob is 23-25 then damnit it should be balanced to be duoed. It sounds really stupid when people say that shouldnt be duoed, like a pathetic heroic goblin or skeleton should be overwhelming death to 2 higher level people but then again its the same idots saying that that also say what most people call frustration is actually fun.
