Nope, it will not solve world hunger either.
But it will give people one less reason to hate each other.
I'm not trying to fix every social problem in the game. I'm just trying to decrease one.
Just because it doesn't fix everything, doesn't mean it isn't worth implementing.
So you are suddenly the definitive authority on what MMORPGs must be?
Yes, I have considered that.How exactly do you propose SE goes about doing that?
If a player has the ability to positively impact the group's activity by doing something (e.g. finishing a task faster), then they have the ability to negatively impact it by not doing it. (e.g. causing a task to take longer than it could have taken)
The only way for a player to not get in the way of something is if they have no power or involvement at all. (i.e. They are only a spectator)
The crux of the matter is "obligation". Can I give away all the money in my wallet to some dude on the street and make his day better? Sure. But no one will fault me if I don't.
Current MMO group content involves a lot of "obligation", you must do this, you must do that, ...
Imagine group content where you don't have to do anything you don't want to - the only one who will suffer the negative consequences will be you; if you choose to. It will be nice if you did but no skin off anyone else's back if you don't.
