I'm an avid fan of Warmaster. I use the Battle of Five Armies set as my base rules, which correct the errors in the original rule book (though for the Warmaster "Old World" GW setting and forces, the corrected army lists in the errata files are necessary to have the proper stats, etc.).
In the Battle of Five Armies, pursuits can continue without essential limits— thought they typically resolve by the time a third one would happen anyway. Advances can only happen once in a combat phase.
I find the above realistic, as a pursuit is basically the response to a fleeing enemy, which can be devastating to the enemy but also pull the unwary commander well out of effective position for later action— which happened in numerous historical battles reflective of the assumed medieval/Renaissance period of typical fantasy settings. I see no need to curtail pursuits.
In any case, a great game. I just put on the Battle of Five Armies at my local con : link
I actually find painting 10mm much easier than larger scales. It's about spot color, not detail. Yes, talented painters can still use highlights and sharing to produce amazing results, but for tabletop warfare you don't need that to have your forces look good. Pick a single color for the clothing and capes, tan or brown for the leather and wood bits, metal for the metal bits, flesh for the flesh bits, and black, brown or a bright pale yellow ("French vanilla") for the hair (if any) and you're good. Hit with a black or burnt umber wash for shading. Done. Base it and put it on the battlefield!
