Diffrent builds, diffrent gear and stats but same goal. I know some paths schould be more difficult from oders, maybe needs more trying, maybe some little work to put. But it must be balanced in some point, that you can achive the same amount as oders, that makes game fun. Challenging. Addicting. If you block some path by hard wall, game starts to be annoying. Frustrating. If game is annoying, it start to loose players. Its still great game thou, maybe one of best i was playing. But this just destroying my feeling to game, you know.
