Just played a game where it things seemed a little off. Flash when it should be on cd. Ghost sound when nobody had ghost...
Are you checking their items? Maybe their items have actives?
Perhaps someone was running 21 in the Defense tree?
15% CDR for summoners OP!
Edit: what V he said
You meant 21 in utility. And who does that anyway?
Was there a Blitzcrank? His W sounds like ghost.
Not related to the problem: this got fixed and bans got handed out in a big hurry. But still relevant to the situation.
