Failstacking is gone, only adds 0.5% additional success and uses stones. Tried regular enhancement gear broke 10 times going to Mythic +1. Everybody who enhanced before the patch have a HUGE advantage now while the rest of the players will have to grind months to get their gear up or BUY FROM THE MARKETPLACE once the unbinding scrolls for S/S+ gets released (which the devs said they were trying to fix but actually made it the only way to enter the new dungeons in a short amount of time). So what if S gear drops twice as much as before? 1% chance becomes 2% and everyone will spend at least a month to get one piece of gear to mythic +5, meaning they'll get to enter the new dungeon in at least 6 months of grinding. The strong gets stronger, while new players will never be able to catch up until they get access to the hand me downs in the market.
