First of all Thank you Vrakthris to take this problem seriously and for your responses to our questions!
Im from EU… I’ve been playing this game about 19 years since the 2005 EU launch.
Good to see the Forum is still alive. I did this achievs in the DF Season 2 / Season 3 and I also got the stones so I really hope players who did this achievs under the DF Season 2/ Season 3 will got their tmogs.
This bug with the DF Season 2/ Season 3 achievs and the current situation when players obtaining time limited seasonal items from legacy raids was very confusing for me.
I sent multiples bug reports retail/PTR, I also mentioned this bug in ticket at the time when the Rated PvP buttons turn to grey, I wrote post on the Forum (posted on EU forum too) about that…
If it’s help this is my bug report and also contains my point of view:
I have only 1 question and also some suggestions about the current topic:
Players who’s did this achievments outside of the seasons can keep this rewards or not? I just ask because the FOMO around the MoP Challenge Mode sets, Mage Tower Appearances, Elite PvP sets…etc…
Suggestions : If WoW keeps this stone system in the future to unlock additional tmog effects/appearances I think the SL Mage Tower set system would be better for this.
That means you won’t get any item to your inventory bc the system will instantly add the tmog to the collections.
Big Thanks to Vrakthris and for All who joined to our bug conversation!
