If u want to slice terminals to get higher mission rewards there is a trick u can use to get increased rewards twice. First you need to know that u can take two mission at once (many people don't know that). If you have sliced a terminal and use it u should see a box that shows mission name, rewards and so on with slighty increased rewards (about 50%) due to your slice on that terminal. Now DON'T click on the "Refresh"-Button otherwise you'll get the normal rewards again. Then look up the two missions you think are the most attractive and accept BOTH of them...and that's it.
