Here's an idea, give us some daily mission that has us going to a system to find 5 to 15 data samples, and have them based on what type of researching they're for, like one system can be for Radiation, Mineral, and Alien Artifact samples. Also, maybe when you add the update to the Sol system so we can go to just about every planet, give us a mission that we can do every day or twice a day that we can go there and hunt for data samples, so those of us, like me, who didn't save a lot of our data samples early on in the game, can catch up on that, instead of having to spend a ton of money to buy those data samples we need.
You can farm Delta Volanis, or any of the other clusters you've been to already, at any rank. Just enter the instances, ignore whatever it wants you to do, and scan all the anomalies. If you want a little SP along the way, take an explore mission for the cluster and just complete the "scan anomalies" missions when they come up. "Aid the Planet" and "Scan vessel" missions are also simple and quick to complete as you're scanning all the anomalies in the system. It's not a dedicated "go out and hunt samples" mission, but it's pretty close.
Yeah, I do that, but some times I'm not quick enough to get to the anomalies before some one else.
I like farming inside the missions as much as possible for exactly this reason; plus in an escort or shuttle you have the scan area feature to find the next anomaly and don't suffer from the massive turn rate nerf out in sector space.
