I dont remember where, so sorry...no link. BUT a red poster mentioned a funny thing happening in testing the involved a NEW SHACO ULTI.
yes - the story, if I remember correctly (and may a red come down and set me straight otherwise) was that it was a projectile ult of some kind (there was not much detail) in which Shaco became the projectile for a period before making a clone (i think it still made a clone, cant remember)...any way, the shaco player for the testing fired himself, and yasuo threw up a windwall...and no coding specific to this event had yet been added, so the shaco player was not even killed. He was deleted from the game.
So, what that tells us is: 1) must be fun to be a pre-beta tester for riot, seems like fun stuff happens. 2) they are looking into shaco changes :D
