When they where intreduced, a scout unit that buffs nearby units with an aura seemed very promising, I thought there would be different upgrades you might get, with different buffs (attack, armor, speed etc…).
In reality there is only one upgrade you can get, and it only makes the already existing speed buff stackable. Reaching a nice 10% which is on par with other mythic upgrades.
Having only speed as a buff is fine, but does 5% for a fragile unite that costs 8 favor worth it? Is it good that its % based, thus mostly usefull for fast units? (and melee ones as kitsune are melee themselves)
