If they would give us a good reason to actually run the Foundry missions (as opposed to just doing the quickies for the daily), I think they could really get away with just giving us the grindy stuff. It would be pretty lame, not paying folks for coming up with the real content and all, but at least there would be content, and some rewards for doing it. Even just xp and a random leveled item or a bit of dil (like 100 or so) would be worth it. But no, we can't even do that.
The drops inside the Foundry mission, including xp, are better; but without dil it doesn't help capped players, and without that up-front promise people don't take the chance of a bad run of the RNG.
