14 level 4 RCs on EI, 2 of them SF
17 level 4 RCs on Atamara, no SF
16 level 4 RCs on Belua, 2 SF
and so on
Many of those centers are filled to capacity, except on BT.
So..2-3% of recruitment centers on each island is level 4 and out of those SF accounts for..pretty much nothing. Really, this is just adding something to the game to fix something that isn't a problem to begin with.
