Blizzard has replied to some concerns about Classic Hardcore around Trading and acquiring String of Ears.
Thanks for the post Azelon. Let’s see if we can dig in with some answers:
We can start earning trophies for “String of Ears” at level 10. But 2 friends can level many alts to 10 to increase the stack count of each other’s mains. Leveling a character to 10 is easy and fast so they are “disposable”.
