I remember me and my friends making fun of him, generally making fun of everything in the story from lvl 1-80, especially the fight against zhaitan was just too goofy and cheesy for us.
But now, with the game developing and getting better (imo) looking back Trahearne's death feels kind of bad. Almost like the community killed him, instead of Mordremoth.
The same goes with Scarlett of course, however, I personally feel Scarlett died a good death.
Trahearne totally got mutilated. That guy was a firstborn, he belonged to a rare line, and probably was destined for big things. He's big thing however was to get entangled by Mordremoth, consumed and then being forced to sacrifice himself to end the Jungle Dragon.
