I kind of agree. The engine would have to be really robust though. The engine now is basically a modified version of the Warcraft 3 engine, which is why there are some limitations.
But, just imagine if Blizz announced they’re gonna create a new engine similar to Frostbite or UE.
It’d be sweet, but the current engine is great because it runs great on really anything (except when flying over or running through Suramar. FPS drops everywhere).
