I only spec'ed up into the things that I actually wanted to use...
So, I'd only raise strength up if I needed more to wield a weapon.
I think I left my faith at 24 so I could use all the healing spells and the shield spells and that was enough. Plus there was a weapon that required higher faith too, so that worked out okay.
I think I focused on INT and DEX anyway, so the magic spells weren't an issue (crystal homing soul mass was the shit).
Pyromancy is always open too, should you spend the souls to acquire it, there are no leveling restrictions.
When I play again, I'll probably do the same. Having the ability to have a bunch of spells/miracles equiped and still play how I want has always been my MO in the souls games.
