1) Yes, in the video you can even see the names of the people with 39 defence spamming "3 9 D E F E N C E"
2) Supremacy only has 1 person with 30 defence (His RSN is Ancients) and he was not even present at the prep. So no, Sup did not break any of the rules that were discussed before the prep.
Tbh, I don't even know why clans even give CP events. 39 defence is not and will never be a "pure" so why even bother prepping this so called "pure clan" if half their ranks are rune pures? Clans need to stop letting CP have their way and just refuse to give them any events. This is the only way to stop this disgusting cancer from spreading.
