Hello! in season 3, they did attempt doing this, but they removed it after in season 4 since in season 3 peoople complained how it was just a box compared to wilderness (at that time), now wilderness is kinda a joke compared to what we've had in the past. i don't think this is a bad idea since some players like having the "hilla"/terrain in wilderness (when it was still there), and some like having a flat area to pvp in. however, I'm not certain it'd come back since it's been this way for 5 seasons and most players do wager duels if they want something flat.. I think readding it would make it dead like it was in season 3 while wilderness is where majority of players are. overall, i am +1 and dont see the harm in adding it.
ik what season2 was, but i was mentioning how season3 had both the wildernesss and the dome, and players seemed to not like it as it didn't get used as much compared to wilderness hence why season4 on, there hasn't been a true separate pvp warp
