Hey, I fused all of my other MPQs together to make this MPQ which removes STV and Swamp Of Sorrow trees as well as nearly all doors in the game. Various doors you can pass through include - Scarlet Monastery doors, Sunken Temple, ShadowFang Keep, Gnomeregan, Stratholme, Dire Maul, Blackrock depths doors/safes/vaults, Caverns Of Time, That door you need to be a certain rank or w/e to pass through in Dun Morogh and lots more!

I havent tested the swamp of sorrows part out but if anyone that is already there/ nearby could take some and host them I would be really greatful and give rep
