I am not sure if I am the only one to report this and if this is a repeat then my apologies....
Since the new updates have been moved over to Holodeck I have noticed that when I run missions for the diplomatic corp I am still getting only the 10 xp. This seems very bad since you can send DOffs to run diplo missions and get at least 3 times that amount. This is further compounded by the huge increase of xp needed to move up levels.
I would have thought that any missions personally run by the char for the diplomatic corp would be worth more xp. So by having this in place, Cryptic is removing any desire to do anything on that side except sending out the DOffs.
The other thing I noticed was that when I was granted the xp it did not add to my total xp amount listed on the DOff screen. So either it is broken and not counting any of those missions or it is doing some background calculations on a different xp scale which would be useless and troublesome trying to maintain two xp totals for moving up the levels in diplomacy.
