Petting the Tigers in Shar Vahl Divided is not giving faction hits after the Patch. Emotes seem to be missing as well.
I know this. I went back again, just in case. I /pat them and all I got was the standard emote that I pat them on the back. Nothing else. After a series of pats (7 or 8), I finally got the faction hit and proper emotes (purrs heavily, etc.). So, it still seems to be bugged, as the Faction and Tiger emotes are not happening consistently.
You must be visible for /pat to function. There is nothing broken about this as result of the latest patch.
After the round of patting noted, where they started working again, I have had no more issues. Bug resolved, if there was one.
