OK I have some suggestions, a few have been mentioned befor
e but oh well.

In terms of gear.
5* spur line weapon, it may be hard to think of what properties to give the (insert the name here) but the lack of one has made the spur line overlooked when found it doesn't go "all the way". I can't think of properties for it, but I hope you guys can.

Cold Iron Carver/Vanquisher needs a major buff. There is statistical evidence in other threads so I wont get too much into that, but it seems there is a 30%difference in the Leviathan Blade and CIV. First, making that gap simply 15% would be good. Second, the CIC has a Unread bonus high, so it is only logical for the CIV have a very high bonus.

We need more weapons to dish out shadow damage with. So far we only have: Faust line, Nightblade line, Blackhawk line, Shadowtech line, Toxic Catalyzed, Dark Reprisal line, Graviton bomb line, and the Dark matter bomb.(as far as I can list off the top of my head) We want/need more swords for this damage type(oh yeah, as well as piercing swords).

General other stuff,

There should be an alchemy machine in the Hall of Heroes, simple as that.
