The fix for hearing enemy's sounds through fog of war went out with this mornings patch. Woooooot!
We had to fix this on a spell by spell basis, so there's always a chance that some slipped past us. To help make sure this bug is completely squashed, please report any sounds you are able to hear the enemy team make through fog of war on this thread. If you don't know the exact sound, but know the champion, tell us that and we'll sweep the champion and find the offender.
Just to make sure we're all clear on how things should function, you should be able to hear your own skill shot hits sounds, as well as ally skill shot hit sounds, in FOW (Gotta love throwing a cleaver into the brush and waiting for the squish). Please only report if you hear the other team make sounds through FOW.
Hope you guys all enjoy Season One, I'll see you guys in-game!
