So I'm waiting for 5 more UISO to fight Loki, then I need 1/2 a star on 8.3 to have 4/5 stars on all three Spec. Ops. missions for the last Lockbock quest. It shouldn't take me more than a day or two at most to finish.
After, there will be 7 or 8 days in which I don't /need/ to use any UISO. Is it worth still collecting 50 each day to get ready for the next Spec. Ops., or do you get a set amount at the start of each new Spec. Ops. mission?
