Just failed my first Dragon and also the first time I have been in a party while trying to kill it.
All the other times I had success because I was solo the whole time and not in a party.
The main reason I have always gone solo is because I get more motes this way.
I will never be in a party again in Mabar. I do better solo.
I experienced this lag you all are talking about for the first time and I was also in a party for the first time.
Just my thoughts, and I think Turbine can learn from this, since I have gloated the whole time I have not had any lag, but also this is because I solo run Mabar.
I am the Red guy who is solo in Mabar, but in a party I am this!
