I cant believe people are so hot over being able to making good items. Perhaps I am maybe just too liberal in my views on this but I say if the system allowed an item to be created then anyone has the same chance to create good items and it all adds more playability and things to do in the game. There is no need to nerf stuff, just let it happen.
The whole "2 mythic" thing is a storm in a teacup IMO. No one has 2 mythic on an item, there can only ever be one. You could argue that bezel should remove the added slot when removed, but tbh the fact that anyone can do this should be seen as a blessing, not a curse. We can all do it if we get the bits and pay the GG.
The way I see it if there is a system that allows a mythic stat to be removed and placed into another item, and considering the cost in GG to do this, then people should be able to use it in any way the system allows. For instance, adding everlast to upgrade and then replace it with bezel is how I thought this system would work in the first place. Its not a bug and everyone can do it, so I think there is a lot of people hot over nothing. Just go with it and enjoy the new feature.
