Since this build was done on a full player damage difficulty game, you're forced to not get into the thick of things. Even with the best lordly armor set, you die in 2-3 hits anyway.
Outside of that STR/AGI builds are fine but since Qualis Gem elixers exist I generally avoid pumping anything other than INT
I always play 100% player damage and have been using Polearms as a primary weapon. My character does fine... I topped 660 kills in a defensive siege and rarely get under 10% of the kills in field battles even when I am playing extremely conservatively. I modded my game to have infinite reinforcements, so "10%" frequently means 20-50 kills. With how I prefer to play, I actually see this as optimal.
With best armor you aren't THAT fragile. I can take quite a few hits and I ignored Iron Skin. It's not as though you are always facing 100% elite armies, and even when you do they frequently do dumb things anyways. (Like try to CQC with a Lance...)
My character is frequently the best anti-knight unit on the field, which helps early game (when non-crossbowmen are likely tickling knights, and your troops are wasting attacks against armored horses) and when I deploy heavily ranged armies. I just kill all of the knights while they are trying to kill my troops, works splendidly... Especially as my ranged troops frequently run out of ammo due to my play format.
Knights lack the maneuverability to defend themselves if they are bogged down by troops, and even if they can somehow defend themselves the horse is likely going to die anyways.
You can attack a lot of enemies without retaliation when you have 200+ reach and troops to serve as a distraction. Later on you will likely be OHKOing everything anyways, especially if you have Ruby Glaive.
If you want to be a martial Lord I do believe that a +200 reach Polearm and/or Bow are the best primary weapons. I generally go Polearm if I intend to do heavy foot combat, and bow if I intend to do heavy mounted combat.
