Since when do I get Deserter Debuff for leaving a finished LFR wing?

[Kozzae-doomhammer (Kozzae)]

Harsher penalties for People Farming The Sacbrood please

We’re currently working on a hotfix that will implement the Deserter debuff for players who leave a Group Finder dungeon early. This penalty will apply to early leavers in all Group Finder dungeons, not just Ara-Kara, City of Echoes. Thank you for your feedback!
