This post doesn't add anything useful to the discussion. You claim to have solo'd a boss but then don't give any details and then congratulate someone, which should have been sent in a PM. If you would like to post how you solo'd it, etc. that would be most welcome. However stating that you did it with no other information is not.
I wonder if anyone has soloed Trial of the Champions heroic or if I am the first one who did this. As it is not very hard i would be surprised. But the only Vid i found was Durendils, which startet right after the first rider guys.
