The way this game works with it's instanced content, this won't work.

Do the devs balance content with players having merit point abilities/enhancements, or without?
If it's with merit point abilities/enhancement, it will simply be a requirement for all people in a group to have their abilities/enhancements.
If it's without the points, then a group with full points would just make the content easier. And would proably still want all their members to have the abilities/enhancements.

The only place I can see this work is in an Eureka style content where balance is less of a thing.
