So how can directives both apply to group and solo if all have to be meet for an encounter to be defeated by that individual? It again shows that focusing only on your self is the key to victory because as your concept scales down, something I've never avoided despite your claims, it would require the directives to also change to not require anyone other then the tank/healer.
Which means a tank and healer just have to survive until their directives become only about them surviving and they can get loot. There is no other way scaling it down to one person will work in your system. You either have group based directives or solo directives. You can't have both when you also allow for strictly solo victories.
This is why you constantly deflectly into "You don't understand" "You are ignoring" "You are pulling it out of your behind" instead of actually trying to improve your idea and correct the flaws. You are no better then how you think of the Blizzard devs. You aren't interested in trying to improve your idea and make it work. You truly to honestly think your idea is the best thing ever with no flaws. That is the type of arrogance that leads to incompetence.
