But it affects metrics like play.
If tomorrow blizzard came out and said you can obtain any aotc mount any ksh or any glad mount two years after its released that would tank the amount of people actively engaging in content. Literally would probably kill the modes because people wouldnt bother now if they onyl have to wait months until next expac to get them.
Things like aotc ksh and glad mounts, mage tower, elite sets, patch specific content tied rewards shouldnt be touched. It devalues the time of those who specifically engaged in said content at that time for the reward
