Another case of dumb dungeon kicks

Leveling an alt tank and get Zul'Farak, roll my eyes and get slogging through it. As per the usual ZF, the group manages to body pull extra packs many times as we progress to the first split. Now I go left to shortcut to Gazrilla, stairs fights, and last boss so as not to spend too much time there.

Now this is where the first of any kind of "communication" occurs: after someone notices I go left at the split I hear the minimap pinging (not the newer ping) and within 30 seconds I'm kicked from group with a 30 minute penalty. No text, no emotes, no nothing, just a 30 minute timeout.

I get 30 minutes now to wish ill on that group and rant on reddit. Something's gotta give Blizzard.
