Vit vs. STR: A note on Stats
As it's been kicked around some more allow me to elaborate on your stat choice: Stack VIT or stack STR?
Simply put, stacking VIT will gimp your enmity gain and damage for the lower levels, as well as during your initial 50s from Titan and AK on down. The Titan fight is the first real DPS check of the game and therefore the ideal is to be STR heavy going into it.
The REAL stat argument is after this point, during the 3rd and 4th turn of the Coils where every stat matters in regard to your tanking damage. Keep this in mind as you level as stat reallocation is simple.
