Looking for some BB Knight build opinions

Knights have a 100% modifier against all sizes when using a spear and mounted, take a look at peco riding. Swords only get 100% on medium size. Like I said before, the Poll Axe wins for utility.

 

You're right about the utility part, but my "100% but both" was refering to medium targets.

It's cheaper to get a high refined Flamberge, so my vote goes for that.

Str 70
Agi 70
Vit 70

Is a SAVD Knight somewhat viable? I have 27 agi on my Swordsman at level 38 and would prefer not to remake the character.

or if i go for 31 agi, would that be alright for a SVD knight? after all it also increases attack speed.

31 agi won't hurt you. In fact you may even have some leftover points to play with after you've hit stat goals for str vit and dex, usually agi is the best choice for smoother BB animation.

Lessen your STR into 60-70 and DEX to 50 and boost your AGI. Your goal is to PVM, right? DPS matters most. STR was nerfed, you may use excellent weapon depending on the type of the monsters.
