OP please link your 13/13H character with a low level boots on (for verification), else your entire argument is void. All I am reading is "I don't do heroic modes, so i'll complain about the game not being challenging." Most people who complain about the game not being challenging haven't even beat normals.
Also the new talent system is not dumbed down, it allows you to swap skills depending on the fight. If anything it's more complex, 99% of people used the exact same talents before this happened.
I could make a post as long as yours, correcting everything you said.. but many people here already stated it.
