Skyshrine (dragon) armor is out of the Halls of Testing (ToV - East Wing). Kael (giant) armor looks like it can drop in NToV and West Wing, at least according to
Allah's archived page. However, the Live version of the page lists ToV - West Wing as the location for Kael armor drops. And you do not need NToV (or any of ToV) for the gems for turn-ins.
I think the greatest thing I'm looking forward to about Velious raiding is the 32kHP cap gets lifted, so these 10second DPS burns on bosses will end and we'll get to see some endurance fights. I will feel sorry for the clerics, gogo CH-chain.
