Unfortunately, a player only has to learn the fight once, so of course there is going to be fewer newbies. However if you can just get a couple of nice people in your group that know the fight and want to help (which does take a little luck,) you can change the description in your party finder. Also the newbie leader from that picture may not have been advertising in mor dhona.

There is no denying that a learning group can take longer to put together, but it's quite doable. Being new to something is frustrating, I hear you. I probably pissed off a couple of people learning what do about that damn wicked wheel in garuda as a melee.
