To Dev:
Please change block values to hit point on helmet, chest and leg, or maybe boot. 3 hit points on the full set is fair. Thank you!
Absolutely not, If anything increase the SBV on the sets to 30+. You can easily get the remaining hit from off-pieces and and trinkets.
There are plenty of non-set pieces to choose for sbv. But hit point is crucial for tanking too. You don’t have much rings or trinkets to choose for 6 hit points minimum.
