Depending on your server I'd say, go for hades on Double GG Weekend and get the missing lf4's aswell as schism crystals for the Spartans( Hades on with 45% Rabate cost you on average +-10-20k ur.)
After that you can still upgrade ur items starting with Drones-->Shields/Lf4's(personal choice which first).
