The Fate of the Jedi books

I just finished the Fate of the Jedi series of books. I found the various powers Luke learns interesting. I find it nice that some of those powers, which could have been an easy way to get things done, were not over used. I just wonder sometimes if there was a need to learn them if he never used them again.

For example, Luke learns the Force Judgement like power of Plo Koon and learns to channel lightning/electricity. He uses that power on the way into the Maw to guide and direct the electrical ion storm around the Jade Shadow, but the next time they enter the Maw it is never used. Now, one reason could be that the first time they entered, Sinkhole Station was still intact and Abeloth hadn't escaped yet, but one has to wonder why there is no explanation how the Sith entered without that training. (Yes Sith have force lightning. But this technique Luke used was referred to as lightning rod because if you do it wrong, you call the electricity to you and fry yourself.)

Then there is the power of teleportation. Luke learns that power and teleports Ben's shock stick weapon from Ben into his own hand. Luke never uses this power again.

The main power, if you can even call it a power, that Luke learns is Mindwalking. This is just a different form of meditation. This appears to pull the user's conscience out of the body into the force itself. Luke uses this power on three occasions. First, when he learns it. Second, when they need to find Abeloth with the Sith. Third, when Luke is going to fight Abeloth in the force realm.

I actually am glad that some of these force powers were only used when they were learned because it would have been too easy to force teleport lightsabers and weapons out of the enemy hand, or force teleport a thermal detonator into the enemy's rank before they can even detect your force telekinesis floating it or pulling it. I think of Doctor Who and how they made his sonic screwdriver basically a scientific magic wand that can do anything. These powers could become like that sonic screwdriver, but they didn't let it become over done. I just wish they would have written Luke saying something about not relying on your force powers or that how the easy, quick way may not always be the best, or that you shouldn't use the force like a tool but let the force guide and flow through you. That way we can see an in universe answer to why these powers never show up again.  

But what are your thought on the powers and abilities Luke and the Jedi learn throughout this era of books, including the Fate of the Jedi series? Do you think Luke could have used them more, or that there should have been a reason never to have mentioned them again after learning them?
