Speaking for me as a mod, I usually try to invis as little as possible.
If someone is stating his point of balancing in a proper way (even if it is beyond any correctness), I won't moderate anything.
The problem is, that a lot of posts are not written like "In my opinion, unit XYZ deserves a nerf because of following reasons: ..." but "nerf that fucking unit XYZ, it's way too strong, there's no chance to win as faction XYZ anymore."
I also will hide posts that attack other members verbally. You can (and should!) discuss, but calling someone a butt crack won't do anyone a favor
Don't get it wrong, ofc I wasn't talking about you.
Even while the discussion continues well and worthy, if there is slightly 1% of offensive content, he just abuse it.
Well, at least I got it at the signature.
