Spoiler

I suppose Disney thinks this is even suspenseful. Darth Vader was a kick ass villain. It was going to be a huge challenge for Luke to battle him. He even got his butt kicked once, basically Vader was toying with him and trying to turn him otherwise he'd have been killed. The Emperor was an even bigger challenge.

Kylo was turned into a pathetic, weak, whiny villain in the first film and lost the first battle. Why is Rey beating Kylo even interesting? It's not. She's already beaten him in the first film...hence no big "climatic" battle with Kylo and Rey.

It is irrelevant due to the poor planning, vision and story telling of Disney.

Lukes piloting skills are mentioned before the trench run by Biggs Darklighter

"Sir, Luke is the best bush pilot in the Outer Rim Territories"
-------------------------------------------------------------------------------------------------------------------------------
The final torpedo shot is already explained earlier before the trench run.

"Wedge Antilles (Red 2): That's impossible! Even for a computer. Luke: It's not impossible. I used to bullseye womp rats in my T-16 back home, they're not much bigger than two meters.

This is setting up the premise to make the ending believable to show that he is infact capable of these feats by doing similar previously.

Han Solo is the one who shoots the other Tie Fighter which pushes into Vader causing him to spinout. Again Han Solo not Luke.

We don't know the true amount of time that passes on Dagobah, so yes it could be a week or could be 3 years, personally i believe it is somewhere halfway. Now in that time we se him stuggle with his feelings, we see him struggle with the ability to master the Force (couldn't lift his X-Wing and without concentration couldn't keep a rock up in the air).

His battle with Vader in Empire he gets his ass handed to him and literally loses a body part to show his struggle and the beginning of possibly crossing to the darkside like his father, that lightsaber battle is epic.

Now Rey on the other hand. We are shown that she is a scavenger on a hostile planet so yes i'm sure she can defend herself when called upon (the stick she carries) but at no point in the movie are we told of her piloting or engineerily skills. Like all lazy writing it is just shown without explanation, she gets in the Falcon and can fly it like she has been doing it for decades, it is not believable. She can fix the Falcon with an idea that one of the original owners (Solo) couldnt figure out, again lazy writing just to show us again how awesome she is.

She literally receives no formal training, absolutey none what-so-ever in any shape or form in "The Force Awakens" but is able to beat a trained sith with a weapon she didn't even know existed or had handled before leaving Jakku. She also managed to learn Force Pull/Push again wthout even being told she could even do it which also includes mind manipulation, again a skill she didn't know existed but knew how to perform, hmmmmm.

This then continues into "The Last Jedi", we still see no formal training of any kind apart from hinting she may have read some books and standing in front of a rock for 5 mins weilding a lightsaber, i could do that but it woudn't make me a master saber expert like she is (see pretorian guard fight).

Rey is a lazy written character just to fill the "strong female character" agenda and because of this, this trilogy is worse than the prequels. For all there faults at least they had a purpose, a story, an ending.

This new trilogy is just a mess of ill conceived plot points and easily the worst jedi character ever seen in the Star Wars universe.
