Re: Spartan recruitment limit. It will be removed with the hotfix (just fixed it now). Thanks for pointing that out.
Re: Pike phalanx, we are looking at further tweaks to it with this next hotfix update. But spartan cavalry are fairly week cavalry and more skirmishers than anything else.
Re: AI Armies, the hotfix has changed the AI recruitment and hopefully improves the armies that the AI creates. We will need to test more to see if it has actually worked though.
Thanks for the feedback.
