Anyone arguing that the feature which is essentially the 'Zombie' talent is detrimental to the character is just dumb. It's really powerful. Anyone who played OS 1 enough knows this. Getting it for free is really powerful.
Will there be some downside? Yes, that's the point. The whole point of the Zombie talent and now the undead race is that it changes the gameplay dynamic a bit. It gets less simple, but if played properly, it can be more powerful. If you don't want the Zombie talent, you don't skill into it. If you don't want to play undead, you don't play undead.
Why is this a topic worth crying about? You have the complete freedom to play however you choose to.
