Any chance you would consider placing all your map variants into the empty space on their corresponding battlegrounds? I'd do it myself but their isn't a list-file.

Any chance of changing the lava and slime to look like the ones from WOD? Stygian's WOD Lava/Slime patch looks better than the included lava and slime here, but the water here is beautiful.
I can confirm, the water is green in stormwind city canals, and dalaran. Also this house in Teldrassil. I was unable to get the white water issue in Darnassus.
