Per previous Dev comments, Foundry missions are supposed to award a certain amount of xp for how long it takes to complete the mission(on average, not per player, which prevents someone from just wasting time and getting xp for it). Is this still the plan? If so, is this going to be tested before going live since their considering going live this month?
The WORST thing they could do is push THAT particular feature to live this month (if they will send out foundry at all) - it is a major point for balance to be checked out before being realeased on mass.
For example, Blizzard released their Guild Leveling system without such testing (in particular, XP via guild achievements and missions). It was completely untested on a wide enough pool of people and lead to the system being exploited. When they rolled back the effects it caused a lot of outrage, not only for doing it but because people felt they had been lied to initially over what Blizzard said the system would provide.
So Cryptic (getting back to our beloved mmo) should test this as much as possible on tribble first ofc. They need some automated system no doubt that can determine if a mission is worthy of receiving of getting X, Y or Z amount of XP, and/or DipXP and/or EC etc.
.. inveritably, such a system would still fall prey to the requirement to be mass-tested, so I only hope that they do it in such a way that a 'rollback due to exploitation' would not be required once it is let loose on Holodeck.
