I feel the loot system is great like this. Gives everyone a fair chance and reduces the "Omg, DRG loot drops all the time" excuse. While I personally in a static I feel there are zero issues with this. Run each floor ~4 times each week and everyone has the thing they want.

If you are worried about not being able to get in a static due to your work time you can always MAKE YOUR OWN static. Have a static that fits around you not some one else. I am sure you will find players that will be able to do stuff at that time.

Side Note: My GF is not in a static due to her work, but I help her with your DF runs all the time. Bring some friends (or close FC members) to fill in the PuG spaces to reduce the chance of other players rolling on something you need. She has zero issues with her tokens.. then again she is VERY lucky roller.

Best of luck on your DF Token farming.
