thanks for the replies, my post was due to the fact, that actually playing as the gauls, i miss some type of units. I forgot to mention a standard skirmisher infantry for the gaul. it was strange to me thinking of a "green" faction not having any skirmishers. Yes the Geroas have some javelins and so the Botroas, but they are just 2 or 3 javelins, and they have not the skirmish mode ability. there are the Naked spearmen, who to say the truth, dont appear to me, to be some good skirmishers. Im not discussing history, cause i have not great knowledge about Gauls, (i have almost no knowledge). So i live on some of the myths i had about those peoples.

Now regarding Cavalry, i Know Brihentin are very strong, but they are not very relibles, cause they cost a lot. ( i look at them like Elites, so i dont train them a lot)
Even with that huge map i posted i cant afford more of them in my armies. And if i can train more, it seems to spoil the game, cause like i sayd i see them like elites.
So i was thinking to a more reliable cavalry (see, less expensive) that could substitute the Leuce Epos after the 2ns reform.
Now in my campaign i have only Leuce Epos as cavalry. And that seems quite poor to me... (ok, they are great cavalry but id like to have more variety)

Regarding infantry it's the same than the Leuce Epos.
I dontlike to have army composed only of Neitos. it seems to spoil the game to me.
usually i put just 4 neitos in the army(as flankers). The rest are Spearmen.
Now those Geroas and Galliche, are good to sustain the enemy for a while, but i have to be quik to flank with Neitos, if i dont want them to rout.
So i was thinking if there were more professional infantry, i think this professionality should regard the Spearmen too. I dont see the Gaeliche very professional...
Now imagine this warlord paying the soldier armaments. Why not paying some hemlets and a leather curass for the spearmen, who are the bulk of the Gallic infantry?

Ok as i sayd im not expert in gauls, and im not expert in military history at all. So lets take this consideration for what they are. Just consideration from a gamplay side.

Anyway if history-side there are no prove of a more professional cavalry, and there is no space anymore for other units, nevermind.
