My post there:
Art direction would be one of the following: masamune shirow, or the lead artist of macross 2, or the lead artist of escaflowne
technical artist/direction: the guys from Lineage 2 or Aion for making gorgeous games run on very average systems.
combat/loot design: the designer of MechCommander 2 (love that inventory/skill design and it would work so well in an mmo) plus the mmo would be a small squad tactical game a la Warhammer Retribution or Mechommander 2 or who would be better to handle the companion/pet/mercenary of a traditional mmo?
experience/leveling systems designer: the guys responsible for Diablo 2 (near infinite replayability, minimal level grind until much higher levels that weren't necessary to reach but still decently incentivized)
level/auto scaling systems designer: the people responsible for the current system on PTR Diablo 3 (finally an auto-scaling content system that works, let alone works so well)
class designer: the people from Vanguard or the people from DAoC/WAR
dungeon design: the people who designed WoW's Deamines
theme: steampunk, magitech or more likely a hybrid of the two
Crafting: the crafting designer from Asheron's Call 2. Just the best system in that you salvaged junk loot; crafting while adventuring and you could critical craft for better than average crafted item stats for the level
