[EB]3v3 or 4v4 Historical Battle Idea

[Brave Brave Sir Robin]

I've already posted a list with EB units in page 2...

Yes, but you didn't actually convert it into in game units with unit sizes considered and such.

Ok, this was a bit tricky and I'm sure there will be some varying opinions on this which I would love to hear such as "Robin, you are an idiot." Anyway, this is just a basic outline that I put together in 20 minutes in custom army construction

Map: Unknown though it there are any ideas on how we can possibly implement a river and flat map together I'm all ears.
Weather conditions: I read that there may have been a drizzle during the battle which impeded the compound bows of Antiochus' skirmishers. I'm all for this to help balance a bit.
AS armies
Center:
4 Klerouchoi Phalangitai (1 with captain)
9 Pantadapoi Phalangitai
1 Thanvare Payadag
1 Thanvare Parsig
1 Toxotai
1 Gund-i-Palta
1 Toxotai Kretikoi
1 Shuban-i-Fradakhshana
1 Elephantes Indikoi

Right:
1 Somatophylakes Strategou w/ 1 chevron (Antiochus and captain)
1 Hetairoi w/ 1 chevron
3 Hellenikoi Kataphractoi
1 Argyraspides w/ 1 chevron (I'm torn between these or Hypaspistai because the use with cavalry would seem to indicate the latter and Hellenic elites were often confused by historians)
1 Dahae Riders
1 Galatikoi Kuarothoroi
1 Thanvare Payadag
1 Gund-i-Palta
1 Elephantes Indikoi

Left:
1 Hetairoi w/ 1 chevron (captain)
3 Hellenikoi Kataphractoi
1 Galatikoi Kuarothoroi
2 Keltohellenikoi Hoplitai (these are the cappadocians supposedly armed in galatian style)
1 Misthophoroi Uazali
1 Anatolikoi Phyletai
1 Hetairoi Aspidophoroi
2 Cuerpos (galatian cav is mentioned and I think the heavy cav would be overkill here but again, your suggestions are requested)
1 Shivatir-i-Pahlavanig (representing absent camel archers)
1 Harmata Drepanophora
1 Elephantes Indikoi
1 Thanvare Payadag
1 Akontistai

Roman army
Center:
1 Equites Consulares (captain and Lucius Scipio)
2 Hastai
2 Principes w/ 1 chevron
1 Triarii w/ 2 chevrons
2 Hastati Samnitici
2 Pezoi Brutii w/1 chevron
1 Triarii w/2 chevrons (ok with either Triarii or even Pedites here)
2 Velites
2 Akontistai
1 Toxotai
1 Equites Romani
1 African Forest Elephant unit (needs to be added to Roman roster)

Left:
Same army except substitute Equites Romani for Equites Consulares and remove the final Equites Romani unit so there is only 1
No elephants
Replace Toxotai with Accensi for flavor

Right: (Makedonia)
1 Hetairoi w/ 2 chevrons (captain)
2 Lonchophoi Hippeis w/ 1 chevron (substituting for Roman cavalry on that wing, plus gives a better chance against cataphracts)
4 Peltastai
1 Toxtotai
1 Spendonetai
1 Toxotai Kretikoi
1 Taxeis Triballoi w/ 1 chevron
1 Thrakioi Peltastai w/ 1 chevron
1 Thureophoi w/ 1 chevron (these three units represent the Makedonian/Thracian mercs who guarded the camp but in this battle may actually be needed)

I plan on editing a few things in the edu as well.
1. African elephants must be given back to Romans
2. Fear effect removed from cataphracts. Fear from properly used elephants and chariots is enough, but from cataphracts as well? Too much
3. Toying with giving Principes and Bruitians 100 men to match Hastati.

As always, give me your thoughts and recommendations. The numbers in these armies favor the AS by about 300 men which is perfect imo. The mnai spent is substantially favoring the AS however, about 10k per army section (or the price of an elephant unit). I can rectify this by giving Romans more men but this would disrupt numbers balance, or further chevroning them up which doesn't seem right to me either. Is there any other way you guys can see to balance this a bit more let me know. It definitely will be a challenge, though not impossible for the Romans. After all, the AS severely lacks mobile infantry and the two wings will have trouble bringing cavalry to bear successfully if they can't coordinate with the main phalanx line.
