you won’t, you should accept current wc3 as it is now, unless you are a melee only player, the core map making community isn’t going to spend a metric boat load of time to recreate everything they already have for Reforged.
telling this to everyone now,
Reforged for campaign and melee
classic graphics for custom games
also wc4 will never be a financial success because the current gaming industry can’t care less about an RTS not when games like overwatch sell 30 million copies or the recent call of duty making over 500 million $ and it was said it underpreformed heh welp some broken expectations these companies have, wc3 is only alive because the fans and the map makers kept it alive.
you make wc4. you just split the playerbase in 2 and destroyed the map making community because the new engine will be too hard for people to actually deem worthy to create maps on.
Wc3 reforged despite of all the recent issues and problems is a love letter from blizzard to it’s small and loyal fanbase. which is rare to happen in these days.
and also another expansion for the game is much more reasonable then a new game.
the face of warcraft is mostly remembered by wow, and it’s a sad fact everyone has to live with.
