If we can find a reptile that tolerates the cold, I say let's build you a god-blooded/sorcery enhanced dino-steed.That gives me a free BP I can spend on something. I could try trimming down something for a familiar. Or put that dot towards command for even more troops, a size 4-5 battle group, or a size 3 with Elite Drill.
As for those that actually got speed ratings, top tier is a Horse or Simhata at +4.
Then I looked at the Lunar book...
We have stats for a Moose and it's pretty good.
Natural Soak of 13, Hardness of 7, Speed +4
Attack is 10 dice at 17L
Evasion is 1, but Parry is 4
Keen Nose Merit for double 9s on scent perception.
Swift-Hooved for double 9s on disengage, adding it to rush requires training to unlock the latent ability.
