I like the multiple banks concept, and an associated AP upkeep cost any time more than 1 bank is kept raised for a following turn. It would maybe have to be the same cost to keep it raised as it does to raise it, because otherwise being cheaper to maintain than to bring up makes it almost standard practice to raise a 2nd bank right away seeing as how no one is attacking in the 1st and maybe 2nd round yet.
So like
1st Turn- 1AP raises 1st bank, 2AP raises 2nd bank
2nd Turn- 1st bank always stays up for free, second/additional banks always costs same to keep up again, 2AP.
a 3rd Bank to raise/keep up would be 3AP obvi
will get my post up between tonite and tomorrow nite!
I like that move through Hop, forcing a reposition! Very cool =)
