Blizz, it is stuff like this that makes all the good will you get from changes go out the window.
Many people have spent tens of thousands of gold on these, and you are just making them useless. Who cares if they make a faster leveling experience faster, who cares if they make any changes at all. We have had these since WotLK, did varying things to earn them before we could just buy and have on all characters, all so we could make stuff faster as we have done these things countless times already.
This is just another punish the player event that is unnecessary and honestly, ill thought out big time. Change this, definitely, you already see many people are peeved at this. At a minimum if you are gonna implement this, give us our gold back. It wouldn’t be hard to figure out, as all heirlooms outside of the rings, trinkets, and certain weaps, had a base gold cost, then refund the same amount for every tier it was leveled up.
Otherwise, if you do this, and just say “them’s the breaks” all you are doing is making people that were finally changing their minds about how you were FINALLY listening to people, quit caring more and definitely will not help your declining subs…
