I did.
Because it was packed with ore also.
crossed my fingers and i got crit rate gloves and speed boots. I spent ore on the chest due to the flat rates and got attack % witht the rework, and the deal ended up pretty decent as i was struggling in some dungeon levels (was worth it).
So, i gess its a matter of luck!
If its a set that you cant acchieve by farming, why not?
