But well, when those upgrades is infusion that worth thousands of gold then it will be different, no one would buy a set of that for each character. So this Armory update forced them to transfer the upgrades each time, or use shared slots ( i.e 2 slots for 2 rings, now it gonna be 6 slots for 6 infusions). For me at least I still have the Slumbering Conflux outside of Armory to keep sharing 3 infusions, but not everyone is lucky to have a spare.
