Putting this link in here as well:
S4 Elite PVP Set - Not Updated to Reflect Winning Tier (CC subforum)
S4 Elite PVP Set - Not Updated to Reflect Winning Tier (General Discussion subforum so we can chat about it)
There is no fine print anywhere stating this was simply PVE S4. This was ‘S4’ (all-encompassing - not labeled ‘S4 PVE’) and you can reference any of the links to the voting, results, so on and so forth in the posts linked above.
Either way, my hope is for Blizzard to communicate why there is such misalignment or what happened in general.
