I never thought the faction with limited roster is weak.
In 8#, i just want to say "Sweboz factional units is lack of good ranged units", and i expressed not clearly.
'I have finished all faction campaigns at least once and i am going to prefer Swboz；
The sweboz units get bonus in forest and can access to high exp units, but the roster is rather limited.Compared to Saba( can recurit Arabian archer-spearmen, a very good low-tier multifunctional ranged unit, which has a longer range than sabean archer), Sweboz factional units is lack of good ranged units(long range/large ammo archer). In my experience, the ranged units are more reliable assault force in battle H/VH campaign( ai receive attack/defencer bonus), for the reason that the ranged unit is not influenced by the defence skill. And in foreign MIC, the saba can recuirit Hellenic native phalanx which is the highest PPR(Performance to Price Ratio) line infantry in my opinion. "

Another question is, the moral advantage of sweboz. The moral of sweboz units is high, but i can't find sweboz has a huge advantage on it. Most time I'm using medium tier(3 level MIC) unit as the backbone.The backbone units of my sweboz campaign in factional roster is germany spearmen, with 11 moral. It's good, but don't have a big advantage over other factional 3-level units. For saba, even the arabian light infantry has a 11 moral.
