Why are there no Gaesatae Mercenaries?

[Thaatu]

Which are better Gaesatae or Tindanotae?

I think they have the same stats, but while Tindanotae are recruitable as mercenaries, Gaesatae are only recruitable by Aedui, Arverni (native MIC 4) and Carthage (regional MIC 4).


Edit: Actually Gaesatae have morale 22 while Tindanotae have 20. So Gaesatae are better.
