3-0 is the default result if your opponent fails to submit, yes.
If he submits late he can lose with a smaller margin, or even draw/win.
From next season every late submission will be a straight 3-0 loss.
I ask you, did you value all outcomes of late submissions the same way? I want to be treated the same way as everyone else. I was penalized and I support that. Now I want to be treated the same way for the round against LFC_Bitcoin, as it was applied to everyone else. I can't see how I am any different?
