I actually dont reccomend full stamina after you reach 30k health. Once at 30k health, distribute into stam/magicka until they are both around 20k. Assuming you mean DK, all of the buffs/utility skills you are going to use cost magicka.
My points are set up like
17 Mag
0 Health
47 stam
Puts my stats at around:
19.5k mag
32k health
25k stam
As an Imperial DK with full gold prismatic enchants, Ebon/Dragonguard/Bloodspawn gear.
