Con - It sucks because of how the physical/magic armour work that you can just grab int/str instead and still be tankier.
I have absolutely no idea at all why people say this. Can someone enlighten me? Because as far as I can tell, the math just flat out does. not. work.
One point of CON gives you +7% health. That is +7 units of survivability per 100 health you have. One point of INT/STR gives you +2% armor. That is +2 units of survivability per 100 armor you have.
7 > 2
So why do people say that CON is worse for survivability when you need to spend three and a half times as many points to get the same +survivability?
