Meddler also commented on internal playtests,
sharing a story about a
Shaco rework prototype that
Yasuo deleted from the game:
"Playtests are usually good fun, though they're work first and play second (really different mentality to a normal game).
Random playtest story from the other day: We were playtesting some possible changes to Shaco's ult last week as part of his rework that involved Shaco firing a missile that he and his clone then split out of once it reached its destination (similar functionality to the current ult, bit more control over placement basically). The enemy team had a Yasuo however, and so, mid teamfight, Shaco ults and then Yasuo windwalls, destroying the missile in mid flight. Since this was an experimental change we hadn't accounted for that interaction and so, when the missile was destroyed by the wall, Shaco went with it, never reappearing. Whole group of playtesters broke into applause/laughter once we realized what had happened. TLDR: Yasuo literally deleted Shaco from that game."
