I like the hunt.
I like the competition with others.
I like that it gives parties a reason to swarm.
I like that there's a distinct feel of rivalry among LS's.
I like that it requires communication with large portions of the community.
I like the rewards ratio. For someone who can clear -most- everything in the game, this is a great way to not wait 12 weeks for gear, and it seems fairly balanced. Sure, if someone is getting full credit on literally every mark, it's a bit too quick, but the neckbeards will always find the fastest way to enhance their gear and rrrrrrage when they encounter the slightest hindrance. But for a professional who can only get ~20 hours a week, it's a great pace for me.
I like that the open world now has some danger in it. Much needed, albeit not what I remember/miss from 1.0.
I like that, for once, there's no "queue us up to do content" thing.
I love the monster designs and mechanics.

That is all.
