I just took the time to read the description for the finale of this weekends event.
"This is it: the final battle against the fierce Ancient Karka on the brand-new Southsun Cove map. Only the combined might of the heroes of Tyria has any hope against a creature this powerful, which means we need you!"
I mean, I'm one of the people that hated the Zhaitan fight and how he looked and etc etc etc. But it doesn't seem right that he's been replaced so easily. I guess whatever rules the crab-people is > elder dragons? ._.
