MoP Challenge Mode Sets/ Mage Tower Appearances/ DF Hero Achievs... What's the difference? Blizzard PLS Fix this!

Dear Blizzard Dev Team!

I sent multiples bug reports and 1 ticket about this bug.
Im a bit confused because the DF Season 2 and Season 3 Hero achievments + the obsidian aspectral earthstone and the emerald blossom dreamstone still obtainable from legacy raids.
I checked the article again: Dragonflight Season 3 Ends on April 22
This article clearly said the Season 3 Hero achiev + the emerald blossom dreamstone will be not obtainable after the season. The link https://worldofwarcraft.blizzard.com/en-us/news/24064845/dragonflight-season-3-ends-on-april-22
It’s kinda like players have still possibility to earn MoP Challenge Mode Sets and Mage Tower Appearances after the expansion ends under 2 sec without any efforts because your ilvl is way more higher than in the original expansion and also you can skip the mechanic of the raid.
I think so many ppls still have a small time to play because real life, work… etc… but in this case I would spend my time with valueable things. If i know this earlier I didnt spend the most of my time to get this time limited seasonal achievment (Feast of Strength) if I can still farm under 2 sec in the next expac…

On the other hand I still would like to get the MoP Death Knight + Hunter sets and some
Mage Tower Appearances but there’s no possiblity to get it right now… what the difference with the hero achievs? So a player who played the game under the MoP and Legion never logged in when Dragonflight is live came back after a break (or new players who’s starting the game) at War Within (they can had Challenge Mode Sets + MT weapon skins of course bc they earned before there’s no problem but) also still can earn DF “seasonal unobtainable items” despite of they didnt play the game in the DF?

The conclusion is: 1. everything need to be obtainable or
2. if something goes to unobtainable it should be unobtainable

Ty in advance for every response and PLS Blizzard fix this bug!

PS: Next time if something goes “unobtainable” after the season ends…but the reallity is different pls make a blue post.
All in all if it’s a “planned feature/conception” not a bug sorry for this.

no

There is MOP classic coming i hope they bring challenge modes back so i can prove them that i can do it so i can collect the transmog in retail for example :smiley:
