Could be Riot serverside problem too. But there was the drophack going around that basically drops a game from the server; basically some type of a DDoS on the server I recall.
Riot sorta mitigated it (so that it should only cause latency rather than dropping people), but this was what it did. So there's always the possibility that someone used it/modified version that still functions and it worked.
No, you still had to qualify for it. Unfortunately 15*7 is 100% so yeah.
100% Champ Cooldown reductions would have a few quite retarded options. Soraka is pretty bad (sit on spawn, spam no-cast time/no-cooldown Wish), Skarner would be retarded, Karthus would be stupid, etc.
Curiously Trynd could still be killed by pulling him to spawn laser which ignores his ult. And with no CDR that wouldn't be very hard.
Nami, huh? And a mermaid. *Insert random One Piece comment here*
