>>77874627Dying in 4 hits of the enemy's most common attack makes a world of difference versus dying in 2 hits because it gives you time to respond. And if that armor can put you up to even 4.1, that is effectively 5 hits.
If a heal pot gives you 2 hits worth of hp, the ability to take 2 hits before you can react and pull back to heal means that if you have 12 pots, you have a safe 24 extra hits worth of life.
If you can only take one hit before the next kills you, you effectively have 2 hits worth of life, versus the other guy's 28.
