Hi Guys, i found a little Trick to avoid the Deserter Debuff @ Endtime, if u dont need anything out of Endtime (like me, im hoping for Well of Eternety for my Casteroffhand :X).
So, just before u accept the Dungeon Invite, mount up, accept the Invite and head to the Teleporter, u have 2 be the First one to use it, if u Teleportet, just quickly get out of the Group (before any1 else teleports to you).
If u done it right u wont get the Deserter Debuff. U still have 2 wait 15 mins for the Cooldown, but not 30 mins.
Not a worldbreaking exploit, but for me its nice and wanted 2 Share =)
