My biggest issue atm is actually leveling.
Since I lack any experience from the earlier titles, I have a hard time predicting which stats I should and should not raise. From the ones that seem generally important for the Warrior class that is. Not gonna do Faith or Intelligence obviously... but the others... for example vitality seems to be important for later on to be able to wear heavy armor but to which extend, no idea.
Guides are hardly helping cuz they explain the purpose of the stats but don't go into builds really...
Atm it feels to me that I am randomly raising endurance, vigor, strength and vitality...
