After all the updates, the simplest of glitches still works.
All you must do is open your Warrock Folder (C:\Program Files\Warrock\Maps)
and rename two folders. Open Warrock, let it fail to load, alt+tab your way back
to the folder, rename them back and You will load the altranate folder, instead of Marien. (ex you renamed Marien With Velruf, and renamed them back, as stated. You will load Velruf instead of Marien)
To make the process easier, and much faster, I made a batch file to do the dirty work for you. There is a readme with this file, use it.
