The problem isn’t the number of new players being recruited. It’s that they aren’t being engaged when they are recruited.
At the moment there is no reason to NOT recruit players and skim corp tax off of them.
Compared to a corp that doesn’t do it there would be a benefit gained. This is undeniable.
It could still be gamed and we could still do better.
Again, the issue is not numbers. It is engagement.
We don’t need an incentive for a few players to play with more alts. We need reasons for more players to play and enjoy the game. What you’re proposing doesn’t promote more interaction as much as it promotes alt corps and bot farms.
