Ok, so I've played MTW a little now, and one thing I've noticed is that manuverability and speed will trump raw power most of the time. Given the bonuses for flanking and readr attacks along with the high imoprtance morale has on battles, the army that can get it's forces into the best position usually wins against a force that should be stronger.
This brings me to the point of the topic. My personal opinion is that good use of Cavalry is the key to success. While only 40 man or less units, cavalry forces often maul and rout much bigger units. When used well, they can turn the tide against better trained and equiped forces.
Likewise, trying to defend against a good cavalry based army seems harder than a missile or ground unit based one. Given their added mobility, cavalry can choose where and when to strike, all the rest of the army has to do is create the opportiunity by engaging the other forces in an effective manner.
This has been my experience so far. Post if you agree or disagree, and if you think that another type of unit plays a more important role in your victories. Perhaps archers are your thing, or spears, or infantry. Keen to hear other peoples feedback from that they have found during their long hours of world domination.
