So far the change has been live for awhile and other patches have went through. It cannot be denied at this point that it is certainly intended by now.
The only change was the 30 minute penalty also applying to Early Dungeon Deserters.
This is a bad faith argument.
Nobody likes leavers either. It makes the game less enjoyable. See below.
So you left, and you received a penalty.
Yes. You will be otherwise put into in-progress raids again and those who finish a whole raid will be prioritised for a fresh run. This part hasn’t been changed for awhile.
Especially it was changed back then to not show bosses killed because nobody would join not-fresh runs or LFRaids would keep stalling eternally never forming fresh runs.
From your other posts you claim this debuff did not apply in the past, it appears to have applied as soon as Patch 5.4.2. from a WoWhead comment:
Even 1 expansion back for Dragonflight at reddit:
Ergo: It is not me who is “gaslighting” it is you who wants to see a change to the game and then making such inflammatory comments.
If you do have feedback about it you’re free to add it through the ingame box.
