I... what?
The name doesn't even fit anymore.
I don't quite understand why you hop around all these themes! The last thing comp players would want is a map with an inconsistent, ever-changing theme! It would be hard to pick out from the crowd, but at least they can still go by name.
I'd say revert to something else, maybe not a theme established by someone else in the custom community. Either develop your own entirely, or just make slight changes to vanilla themes. Gorge could've worked! Or Well! Well... all of them could have.
Stick with what you want, the volcanic theme just doesn't slide with me... too much viscosity.
Ba-dum-tsh.
