I am having the same problem with everyone else only difference is with my boots. My boots have the same stat with every other stalwart boot in AH but mine turned as lvl 52.
Same problem here only difference is I am having problem with the boots. :( opened a ticket and been like 4 days and no response. Customer service is awful :(
I dont think BOP items would ruin the game, instead it will make it better. Also you dont need to make every item bop, just the legendary items(purple ones) that drops in a dungeon or when you are in a group or at least if you roll need. But can give option to exchange between group members for x amount of time.
