I feel like SE could have added Hydra to the Duty-Finder and awarded some sort of tomes for it.... maybe turn it into a like Prime battle.
Most people are already done with their relics, and there's no incentive for people to go back and help with this...
I feel like SE had an opportunity with 2.1 to add Chimera/Hydra... and should have.
They made it easier for people to progress through the game at nearly every other level through duty-roulette.
Chimera actually wasn't that bad, I saw two groups form the other day and got into one of them from shouts in Mor Dhona.
Why is Hydra so much worse for getting people into a group?
I made a Party-Finder group yesterday to try to get it going... and in 1 hour I had 1 person join, he made up some excuse about his FC needing him for WP... and said I could shoot him a tell if I got it going.
