Go full VIT for your 30 stat point allocation. If you want more STR, use STR accessories. With DL DPS accessories, you get 45 STR, and you maintain the flexibility to switch out to your tanking gear. With all 30 pts in VIT, and all tanking accessories, I have 7115 hp, ( no relic, yet). I can easily switch to all STR access when running WP or AK, maintain an HP of 6206, and be at a parry % of 24%. It is much easier to go this route, than to min/max with 30.
