Advisor unit tier list

Has anyone thought about making a tier list for advisor units? I know they aren't the most practical as most fully equipped normal units make them obsolete. Despite this I feel like this could be a fun thing to do. Here is my personal tier list based on my personal experience. I don't expect my list to be very accurate, so feel free to show me your personal tier lists. Maybe we can set up a more conclusive tier list.

S-TIER: Headhunters, Somatophylakes, Armored Elephant,
A-TIER: Gesatae, Pezhetairoi
B-TIER: Heliopolis, Longbowman, Hetairoi, Phalanx, Royal Archer, Royal guard, Desert archer, Scythian mounted archer

GOLDEN HIPPOKON TIER: Golden Hippokon
