Global 820 was pretty active early on, got a lot of rep grinded for most of the masters, but the exponentially increasing requirements are pretty ridiculous.
Zana is amazing - daily mission is a free map, sells maps, and gives you a map device for your hideout that gives you a little free item quantity. Hideouts are so slick - no more "figure out which eternal lab instance" when joining a mapping party already in a map.
Some of the special masters affixes are pretty damn amazing. Hits cannot be evaded? -8 to mana cost of skills? Too bad it's still a rich mofo's domain to really craft something amazing from them to really maximize the benefit - every aug I've tossed at them have resulted in crap so far. If I only got something promising with the aug, could regal it and then craft another mod on it with a master for something nice.
Ele Spectral Throw got nerfed hard, I'm a little upset. Actually, Spectral Throw is still pretty good - but the flat damage auras now are so weak unless you're super rich with shavs and can run low life (or blood magic) with a huge es pool (so you can run 6+ auras). With auras running on mana, the nerf to Anger and Wrath, AND the nerf to the aura passive nodes, they're so weak now.
Man the drops in this game are pretty punishing.
I havent gotten a new 1h weapon in about 15 levels now. I cant even spec my dagger nodes because they just dont drop.
You know about the weapon upgrade vendor recipe? You can use a rare rustic sash and a whetstone with any weapon to turn it into a +80% physical damage magic weapon. A magic rustic sash will give you +60% or so. It can serve as an incremental upgrade if you can find a white or blue weapon of the next tier.

And if you've got masters leveled up, you can add attack speed or flat damage or whatever you want as well.
