what did you grind in shadowlands at release?
later sure, in korthia archives (which were not really necesary, only power that could not be aquired in other way was sockets which had minimal impact) and in ZM cypher (which again, unless you wanted to do things in ZM itself were not necesary...
but at release? no power grind at all... only thing you COULD grind was anima and that did not give you any power beyond 1k weekly which you literaly did by doing whatever you wanted in game, no grind necesary...

do you understand meaning of the word "grind"? seems like not, bcs torghast at release was on weekly lockout (at least the currencies)...
there was literaly no power locked behind covenant rep... if you mean renown - as you clearly have issue with words and their meanings - then you are still wrong as that you literaly COULDNT grind, as it was timegated...
what game did you play ffs? bcs it seems it wasnt WoW:SL...

something being tedious and unnecessary long is not hardcore by any means...
at least not in context of videogames
