Just remember that the class is just the base of whatever you want your character to be later in the game. Your starting class does not define your play-style, so branch out. Personally, I made myself a Cleric-Warrior: High strength and Dexterity with high faith. All hail Lightening Spear! Also lighting infused weapons scale with faith, so level that up if you decide to use the Heide Knight Sword.
