On a 26-30 summoning chamber instance, we were getting constantly the announcement "There are currently less than 16 players in this instance. At least 16 players are recommended for fighting the Spectral Dragon." We gave it a try anyway.
After the doors have been closed, we were 9 people in that instance. This left us at a skeleton crew of 1 per lever, 1-2 per altar.
With horror, we witnessed the announcement "In 15 minutes, the summoning ritual will dissipate and the Spectral Dragon will escape." when the dragon was at more than 50%. Slowly, but steady, we beat him down while he teleported from corner to corner. Then there was the 10 Minute announcement. And then the 5 Minute announcement. In the mean time, I had to abandon my lever to raise a person from another lever. Shortly after the 5 Minute announcement, we finally got the "The Spectral Dragon has been slain."
Thank you, Aelur, Caducea, Darkstaar, Helioblade, Gaery, Mushinzx, Tetrodox and Vadym for contributing to my most exciting and rewarding mabar experience this year. You did a really great job!
