Hello there, I hope this is the right section to inquire about this.
Over the past, there have been a few topics opened about the issue, but none has received a blue post answer on whether it was going to be adressed or not.
As far as I know, mists of pandaria has had four pvp seasons - 12, 13, 14 and 15. In all of them, players that have earned 2.4k rating in either arena or rated battleground were able to purchase the glorious tyranny enchant, or a visually equal variant of their normal dps enchant (such as bloody dancing steel for dancing steel).
With warlords of draenor, enchant illusions were introduced and, from this point, players who had earned high enough rank in season 14 and 15 were allowed to purchase a new item, that would bring the enchant back to them in the form of an illusion.
Players who had earned the enchant in season 12 or 13 - and probably still have a copy of it enchanted to one of their weapons as of now - were, however, left out. Aside from maybe technically, there seems to be no reason for this - the enchant was available to all 4 seasons and the illusion was made available after all 4 had passed - so there’s an equality there. Also, season 13, the tyrannical season, has the same name as the enchant and illusion, which makes it even more justified to be available to players who have put their time into earning it during.
If there’s a technical issue that causes a difference between season 12+13 and 14+15, I and many others believe that it would have been fair to either find a way to award the illusion to all four or none at all - and then make it available for earning later on for example. (this ship has probably sailed)
With the current state, the illusion could alternatively by given out to people who can be identified as season 12 or 13 earners, either logically or by having them contact customer support.
While i know that the enchant was available to season 13 by fact, seeing I have applied it to 3 style weapons including shadowmourne and the heirloom weapon awarded for slaying garrosh hellscream, I base my assumption on its availability in season 12 on other forum posts.
While this might only affect a small portion of the player base - those who have earned the rating during s12 or 13 and still play up to this point, I feel like we kinda deserve to be treated in the same way as those who happened to be lucky enough to have pushed arena / rbg during season 14 or 15 instead (or all of them) - it just feels extremely bad if you see someone else with it applied to their weapons and you know yourself that you invested the same amount of time and energy to get there, yet will probably never see the illusion yourself. (Its a daily reminder really)
Please, please shed some light on the matter and please award your loyal players who should rightfully be able to mog that enchant!
Thanks for reading, greetings,
