I have been playing this game for many years, I have also played the new versions of the game legion,shadowlends and dragon.
But I always go back to 3.3.5 Lich King sooner or later :D the only thing I miss in the game is that at some point it becomes monotonous and you get bored.
I mostly play pvp and I miss the most from the new versions most maps of battlegaunt and rated battlegrounds as well as the smooth running of the game.
It would be great if the warmane team try to somehow improve the game and the graphics after all we are 2024 years it is certainly possible. Adding new maps I don't know if it's possible but I think it will be very interesting for pvp players.
