"You need to atleast play 1 ModMap per Round. Meaning, in a Best of 3, 1 Map is NoMod, 1 is Mod, 1 is Tiebreaker for example."
I think this rule is hard to justify in the groupstages.
Because !roll with determine who is going to first pick a map.
For example:
If I win the !roll, I ban some maps (doesn't matter for now).
But right after that, I'm going to firstpick a NoMod map (the one which is easy for me)
Due to my firstpick, my opponent has to pick a map with mods on.
Isn't this unfair because he might also had planned to pick NoMod too (but another map than mine)
