well yeah i think some of you guys are missing my point, shiny armies would still be the best for big military moves like attacking castles etc, but having light armoured troops moving faster than shiny armoured troops means that, to use an example, if a faction sent out a caravan of 2000 "shiny" troops, it could be intercepted by 3500 "armed" troops and they may be able to defeat it ...
what i'm suggesting isn't to nerf 'shiny' armies, it's to encourage the use of other armies (light, armed, heavy), which are at the moment, Never Used
If you make it so each army has a different strat map speed, sure, you'll use your shiny armies to attack castles / fiefs / cities like they are used at the moment, but for open field battles it might be advantageous to use heavily armed or even armed armies.
