I have a Mace and Shield Paladin warrior with the following:
120 Mace Fighting
120 Tactics
120 Chivalry
115 Parrying
105 Healing
110 Anatomy
080 Resist Spells
(I am getting 50 additional skill points from jewels)
As others have pointed out, the Mace Fighting mastery is actually pretty good and works well in a Paladin type of template. I run with sets of Barbed Whips and Hammer Picks as my weapons. Set will include major slayer groups and the various elemental weaknesses. 150 hit points, 185 stamina, rest in mana. I do not use a refined suit on this character and instead have 45 DCI. While it's very tanky and survivable, best scenario is to have another cross healing warrior with you, although that's a bit of a lost art these days. It can do most champ spawns and peerless content without issue.
This was my first character. I originally started with swordsmanship instead of macing and used a combination of radiant scmitars and long swords. The 120 chivalry is probably overkill, so if I were to make any change, it would be to increase resist spells and decrease chiv a bit.
Happy to give you any other information or answer other questions. Good luck on your adventure!
