Cata already didn´t offer much for PvP players first time around… Tol barad, Oh wow. Which was primarily always flooded with PvE Players that only wanted to raid and do dailies.
Cata is where many players like myself left PvP for good, because balance was uberdog 
and everything that wasn´t arena was even more a waste of time than arena was.
Ergo it eludes me how anyone could have expected it to be “poplar” in Cataclassic with only a small fraction of the 12 million players it had at OG launch back in the day, on top of all of those factors that we weren´t able to forsee in teh day but had to expereince to learn to detest but were already common knowledge this time around going into Cataclassic, thus it was clear tha many wouldn´t even touch it tio begin with, as no sane person would want to experience that a second time… So it was kind of a no brainer that this desolate wasteland was always going to be the outcome sooner rather than later. That’s why i’m not touching it this time around, but instead just enjoying how hyperbroken Firemage is in PvE.
It sucks for those that want PvP on classic, and I truly feel for you. But it hardly comes as any sort of surprise, unfortunately.
Sorry, but this is not realistically going to happen. Retail is almost certailny doing better than it has in years, as more raid and M+ logs are being upped and runs tracked on Rio than at this point during any first season since legion. So this will likely remain wishful thinking i’m afraid.
That said, If you truly wish another WoW version, any Wow version, to die for millions of players, just so that what was always, since the dawn of time and to this day, a niche-community of a few hundred thousand players and is in Cataclassic at best a few ten thousand can have their nostalgiamode PvP “back”… then, and only in that specific case, I´m very happy that you currently get to experience exactly what you´re wishing on others, and hope it never ends for you. 
And, just for the record, *if and when retail dies, I very much doubt that the majority will even consider whatever classic expac is currently offered as an alternative. Because for most of them, the primary reason they aren´t palyinjg classic already is that they already went through it and find the idea of going back to an old girlfriend just to remember how she was a laughable concept in and of itself. Add on to that the widespread impression that classic players are “not the best people”, in no small due to constant onprovoked statements such as yours incessantly wishing some form of ill on retail since classic´s release in 2019, and as a result, simply by perpetuating this asinine “retail must die” hate, you are yourself giving them one of the best reasons to stay away that anyone could ask for: a pointlessly toxic community that is already openly hostile towards outsiders. Because the Hyperminmax PvE Trollhards that require epic Heroic logs to sign up for normal raids aren’t yet doing enough to keep people out. Bravo.
