I stand corrected. I must have read the info on the unit compare tool wrong. I see looking at it now that the Dahae actually have 10 javelins as opposed to 8 (might there be some discrepancy between actual stats and unit compare tool info?), however (if the unit compare tool is correct), the Arachosians do have higher lethality in their primary weapon (1 as opposed to .35). So yeah, my bad.
That said, I still do like the Arachosians a bit better. I've just had better luck using them. The way I take the Indian settlements is with a single purpose built army which receives no reinforcement. The problem I have with the Dahaes is that they (for me) don't last until the end of the campaign, while the Arachosians seem to kill much quicker and don't get banged up nearly as badly, and more importantly, they stay alive to kill elephants in all 3 Indian settlements. But I do agree on your price assessment though.
