Doing this would be in the spirit of the sandbox, where players are the content and players make their own play styles.
Various techniques need to be implemented, at corp/fleet/player levels, to create incentives for fleeting, mentoring, recruiting etc. The ‘Refer a Friend’ program just doesn’t cut it, as it’s not part of the game experience and 80% of the players you recruit don’t make it past day 3 anyway.
Unfortunately CCP thinks ‘giving players tools to create content’ means ship re-designs and weapon balance passes. They need to concentrate on creating reward structures that encourage players to go out of their way to do interesting things.
Take a look at one initiative:
Redemption Road Fleets (Greygal)
Also, look at the long-running Red Vs. Blue fleet wars:
Red Vs. Blue: Join the Forever War
These types of initiatives, especially if more widespread and varied, could lead to exactly the sort of player engagement and new player retention/training/socializing that EVE needs to improve.
Unfortunately, over time, there turn out to be very few individuals/groups who can keep such efforts going over the long term. (This applies to most MMOs, not just EVE.) However, if there was some sort of reward/perk/bonus structure for organizing, implementing, and participating in such activities we would see more of them.
CCP needs to implement tools that give players the ability and incentive to create positive game experiences, not just various ways of making it more likely you will explode alone in space.
