Keep passing through, killing any foes that stray away from the main pack - don't be afraid to enter large melees (chances are you'll make it out largely unscathed anyway). Switch to your hammer/2h weapon and charge through areas of high enemy density, bludgeoning at your leisure. Depending on how many enemies are left, repeat 1-2 more times. Continue on through for a few seconds, turn sharply, and make another charge through like in iii). So long as you're not charging up steep hills, you'll be fine. And don't worry about your horse getting hurt either, it's way to heavily armored for that. With your speed and weight, don't worry about getting stuck in the middle unless facing a group of spearmen more than 5 deep (in which case try to hit the group from the flank). Charge right through - you'll skewer 1 or 2, but more importantly you'll do some pretty massive charge damage to pretty much everyone else. Aim yourself towards right into the thick of the enemy horde (lancetip slightly downward). At this point, switch to your lance, which should couch almost immediately. Keep throwing until you've cut the distance to the main enemy group to about 30-40% left. Aiming shouldn't be overly difficult (your moving straight, sheesh). You should start out wielding your throwing axes, so aim at large groups and keep firing while charging straight. Don't worry about enemy archers (arrows usually won't do significant damage, but if it makes you feel better, hold up a shield). Take advatage of that great speed and durability - start out in a flat-out charge straight at your foe's main group (which is a lot of what you'll be doing - running in a straight line. Also, Paladin effectiveness is secerely reduced on hilly terrain - they're godly over flat ground, but don't expect any Tenzing Norgay action from them. Seriously, who cares though? Anything within a lancelength radius is a guaranteed kill, so that manoeuverablility isn't going to be a *huge* issue.
THe build's only downside is its low maneuverability and tendency to run in more or less straight lines.
It may not be quite as versatile as the Outrider or as manoeuverable as the Skirmishers, but it's still my second favourite build to play as. Paladins have tremendously high attack (potentially the highest of any other build), incredible defenses/health/durability, decent speed and effectiveness in almost all situations = very good survival ability. This build is so massively durable and difficult to kill, you just can't go wrong with it.
The stoic crusader for righteousness of old, the Paladin is another excellent choice for a mounted build, top 3 of any build in my opinion.
