It is feasible to solo, you can still kill mobs can't you?
For it to be not feasible to level solo, mobs your level would have to be impossible to kill without a group.
I liked 11's take on all of this, basically forcing party play. It build a nice helpful community. I don't think a lot of the anti social player's have given into the fact that playing with others is ideally what an MMO is for.
"MMOs are for group play" is a dated theory that fell flat on its face about 5 years ago. MMOs are a videogame where you log in to play and share a world with hundreds/thousands of other players. That is all
. If that, to you, involves a focus on grouping, awesome. If you prefer a mix of group and solo play, that should be fine, too. If all you want to do is log in and do your own thing, there should be abundant options for that, too.
Forcing group play doesn't build a helpful community. It builds resentment and drama. A helpful community is formed when the game is entertaining for a wide variety of people who, because they are enjoying themselves, tend to be friendly and happy and willing to collaborate with other players on a great many things. XI wasn't like that. XI was "be on your best behavior because you need these people." It was a mountain of contrived ******** that the community clings to as truth despite mountains of evidence to the contrary.
There are great friendships and mature, functional groups in every single MMO I have ever played whether it was "group onry" like XI or more open and accommodating to a variety of playstyles and interests like LOTRO or WoW. The only people who don't think the XI community was exactly like every other MMO community are the XI players who don't want
to see it.
It's not the developer's job to shape the community by restricting player options. It's their job to enable the community to shape itself by restricting idiocy and providing entertainment. That is all.
