i think that being able to remove leaders from the pool is a great idea. considering how rare it is to find decent leaders for the stuff you want unless you have their cost reduced, even using the exec order, i think that this would make it a lot more fun for a lot of players. having to wait 30something months for bad candidates to leave, when like all you have is bad candidates, can be really discouraging. have a short cooldown on it if you think it's too good. at the very least, lower the time they stay in the pool to under 10 months. the randomness can be crippling, esp when all you're getting is really expensive, crappy ones. which keeps happening to me...
