Effective use of chariots? (and a few other unit tips needed)

[Mr Frost]

Skirmisher cavallery has no advantages over other cavallery. They are just mediocre

Hetairoi Aspidophoroi {602 Mnai} are cheaper than lancer Hetaroi {1153 Mnai} , Lonchophoroi Hippeis {784 Mnai} , and the Thessalikoi based chargers , can park on the arse of engaged elite infantry and fill them with 600 javlins or put those javlins into elephants before they hit your line whilst still being able to beat most cavalry that can catch them .

The only real question then becomes : can you make better use of Hetairoi Aspidophoroi {with their javlins} or Prodromoi whom are only slightly cheaper ?

When you only have 2 spots left in a stack and muct choose between Hetairoi Aspidophoroi and Prodromoi , against Successor armies it makes sense to take the Aspidophoroi as pike units usually "magically" turn all their pikes to the rear when charged from behind killing your charger cavalry and can take a long time to rout {especially the elites} thus killing more so javlins to their backs {cavalry can flank much quicker and more effectivly than infantry} from a cav unit that can still quickly fight their way through most enemy cavalry and skirmishers {that get in the way of a charge} are a good companion to sarrissa armed Hetairoi .
