It has been suggested to use realism as a base as the mutator is optimized for this mode and changes all the necessary things from realism, it tweaks the settings like the creator changed it, classic runs with some bugs that we noticed during the last tests which was the reason to turn it into realism.
@Kleist: Just contact me, it's new to me that the admin tool is not working, just checked it and it works fine.
@ aaz: if you're not willing to check the mode out just because there's "realism" in the name you missed the sense of this mutator...
As for the others, would be nice to get informed a bit earlier, so that we've at least one admin online to tweak such settings.
However thanks for hosting such events on our server, keep up the good work!
