I just want people to stop using the disingenuous arguments that they care so much about matrix realism but every other aspect of the game can break realism as much as it wants.
I see, and I am with you on that. Discussions of realism are tiresome anyway; at least in the context of things that aren't real, where it is more about makebelieve. The Matrix rules took a step away from todate reality to make the game more fun. While fun is no actual prerequisite for a game, it usually is what people are looking for in a game.
Essence, while not being an unreasonable concept fluff wise, mostly is crunch and a means of balancing. If it is easy, hard or possible at all to regenerate this stat, is simply dependant on what serves the game best in whole.

Are you talking real world here? I'm missing context obviously.
Sorry for being vague there (or confusing

). I was talking real world, yes. Burn-out, transplantations, drugs (and so on), can mess up the balance of your body (and badly so), bringing your immune system to act up or to break down, making you tired, depressed or anxious and so on. There are paralels. These paralels let me think along a course of logic, and use the comparison, to decide, what is believable or not. That is why essence-holes sort of make sense to me fluff-wise.
Funny thing though, there are enough people out there, that find and claim many things of our today world, as not realistic.
I guess I should catch some sleep... I feel like I am starting to ramble.
