i think i "played" with every faction, but these i tested for some seasons, but then leave alone

Saba - no real elite´s, boring unit roster
Pontos - always prefered hayasdan because of there reforms and units
Casse - everytime a slow start, but i think they have interesting units, but don´t like there generals
Ptolemaioi - oh shit, they are too save and rich
Lusitannan - i just like: "Iberia Rising: A Lusitannan AAR" - Chirurgeon
Averni - don´t like them, prefered aedui or sweboz
Pahlava - i don´t know why
