Being hollow reduces your health to 50% in this game as well, I thought.
Well even if it doesn't, the main drawback is that you can't summon anyone, which is pretty fun, but usually it's not necessary.
Also parrying is impossible, I found it more reliable to just block or dodge the attack.
Nah.
Not sure if you have to be human, but I know that more humanity increases your players defense and resistance. Marginal at best, but it's a still a slight increase.
In other words if you are not concerned with summons and invasions the difference between being human and undead is a few defensive points, and to be honest, I'm not even sure if you have to be human. You may just need to have the humanity.
