I know the health regen bonus is multiplicative, meaning the more you buy the less you get each time. For those who have purchased the "extra" 7th level for their faction is it really worth $6 billion?? My faction is screaming for more health regen and I told them we'll save for weeks and probably not even notice a difference.
Please correct me if I'm wrong but it doesn't seem worth it unless you have money coming out of your factions ears...
Many thanks.
