Here is my question. I want to know why I am unable to do the 'Temporal Ambassator' quest myself. I did it one one character, deleted that character, and started a new one, but now the quest doesn't come up. Are we incapable of doing the quest on multiple toons? And yes, I am level 6, so that wouldn't be the issue.
It was transferred to the mission journal and now has a level 25 requirement. You can still get the T3 Ambassador, but the T5 Ambassador was removed and is now available as a Fleet Ship assuming your fleet has a Tier 3 Shipyard.
