Players connot join the party while you are engaged in combat

Concrete operational thinkers aren't capable of understanding the developmental design. They only see the direct consequence to them personally. They literally cannot grasp the overall point to the design. Most MMORPG players are concrete operational thinkers. That is the main problem.

To account for teens' inabilities to develop a working society because their brains aren't developed enough to do so, and yet still try to please them as the major parties in that society...is a difficult task. In the real world they don't have any sort of voice or power, so they don't matter. Here, they matter, but their brains are still too immature to implement everything they want en masse.

This is just one of those things that no. You don't get what you want, because you don't know what you're asking for.

what does this have to do with a game feature thats almost required?
