6-8 legionaries, rest whatever.
I like to go with 2-4 cav, 2-4 javelins, 1-2 artillery if I can.
Oh throw in some spearmen as well if you're fighting cav heavy factions. The more cav the others like to use, the more javelins and artillery I substitute for spearmen.
-E- Oops, I didn't understand what you were going for. I guess the spread was something like 40:60 Legionaries:Aux
When I feel like it, I recruit 1 Eagle Cohort and 1-2 Evocati and rest normal Legionaries. By that point, your economy is probably strong enough to be using only Eagles or at least only Armoured.
