Good job on the Second Binding Coil of Bahamut

[Sessurea]

Didn't they try this with Pharos and people complained?

Actually the problem there was that haukke hm ( one example of the many faceroll dungeons ) was as rewarding as pharos, so people didn't bother with pharos.

"But difficulty vs reward shouldn't be an issue in this argument? The person wants challenge, not tomes!" Well that's just human nature.. Pharos Sirius is still the hardest dungeon in the game, and still isn't as rewarding as much easier, more rewarding new HMs.

TL DR: People didn't bother learning pharos, because they could get a similar reward doing something much simpler. I honestly don't think people found it too hard, they just wasn't bothered due to lack of reward.
