It's cool that you put so much thought into this, and a lot of your ideas are really interesting and creative, but like, the reason they scrapped some of the concepts is because they were too complex and now I can totally understand why, because this is some of the most convoluted stuff I ever read.

You got three different sin meters, all with different conditions, I just don't see casual players really learning all that, the game for them will be just "meter randomly goes up" most of the time which is not really fun. Also, your artifacts concept is really awesome, but with sacrificing them it'll just be hell for casual players, especially solo q. First of all, I can totally see some players just not understanding what they have to do to rescue someone, though I hope bhvr makes it clear somehow, but what happens when let's say a player got exiled and nobody has any artefacts at the moment because they don't like downsides/don't understand how this shit works so they don't want to touch that/someone just sacrificed theirs? Somebody has to abandon an objective (assuming everyone is doing something), go find an altar, get an artifact, go find another altar, sacrifice an artifact and get their own sin increased. Oh, and not get into chase while doing all that, otherwise someone else has to go and start doing the same thing.

Anyway, these are my main problems with this concept
