I muted it, gotta look up my posting history, sec.
Here you go:
I even made a topic in CS about this behavior, topic got locked by Vrakthris, the same CM who posted the November '19 blue post about it:
In their 2019 post they imply it is.
Look, I’m against it, and I sustain it’s an exploit, backed by the game’s CoC (disruption) and their own post regarding the meta philosophy behind it in 2012 (check the CS topic I linked).
However, Blizzard’s current stance about it is “silence” , which implies they are ok with it, so, let it go.
Just take the L.
When people stop playing level cap random BGs due to it, like in 2012, they might act.
Yup, they speak for Blizzard, relaying the current understanding of the set rules, barring dev intervention.
