tank build

can i ask str<vit and vit>mtl which one better and what is mtl effect?

 

Vit>str is good IF you want to be a tank that can do dmg, but, will be effected by ailments which can potentially get you killed.
[And Vit>Str or vice versa shouldnt really be attempted unless you got PCR or thunder axe(both atleast 1s/2s with decent refine) or anything new which l may not know of; which can contribute to lil dmg],
Mtl>vit is good in sense ailments wont effect you if you can get it to 100%,
High Vit doesnt really matter much these days,
If you can get resistances, know what your are doing and time your skills right, even 4k is nuff; that high hp is merely a failsafe INCASE you are caught off-guard.
