Ullanor: The Warmaster's Coronation

Obviously we need a thread to talk about Ullanor. Since it wasn't started yet, I decided to do it myself. To start with, here is what I recall we had as our "for sure" list of Participants:

Wolves of Dawn
Steel Marshals
Silver Cataphracts
Eternal Zealots
Crimson Teeth
Lions Rampant

It was also suggested that we vote on adding either the Thunder Kings or the Iron Rangers. Obviously, as the anon in charge of the TK, I have a bias towards them, but I want to know what the group thinks. So let's start here. Is this too many legions? Legions that don't work out right? Let's get some discussion going.

The Ir are at Ullanor, that's been in there since early on. There was push to get them more involved, but I think it would be better to keep it as a bit of a token force, used for scouting, gathering intel, and causing havoc to the enemy lines.
