I’m talking about his ability to overall be seen as an actual threat throughout the movie. Please, I don’t want to repeat myself on this : (

Well I don’t like repeating myself either but as stated before he was a continued threat to our heroes to the end. His “ultimate” failing being the result of other factors. Other factors you have been actively avoiding. Other factors that have never been in play before a lightsaber duel in the film saga.

I mean if you have to severely injure your antagonist and nerf his abilities so that your protagonist can beat him doesn’t that show how much of a threat he is?

Excuse me, but saying this was Luke’s fault is pretty ridiculous. I’m not even sure we’ve seen the same movie.
Yes, the Walkers have to destroy the power generators, but the Rebels’ objective is not to defend them, but to protect them for as long as possible until the transports are away, because they know there’s nothing that can be done against the AT-AT and an entire Emperial fleet. Here’s from the script:

CONTROLLER: General, there’s a fleet of Star Destroyers coming out of hyperspace in sector four.
RIEEKAN: Reroute all power to the energy shield. We’ve got to hold them till all transports are away. Prepare for ground assault.

And then:

RIEEKAN: (into comlink) Launch patrols.
LEIA: (to an aide) Evacuate remaining ground staff.

They were just buying time to escape, they knew there was no way to win that battle. Luke’s not responsible for any of this, look it up :\

Fair enough the the “Excuse me” threw the hell off lol

For all we know, controlling oneself when using the Force to choke someone may not be easy: he might’ve not been able to stop before killing Luke, but that’s just speculation, or it may take time to focus (every time we see the Force being used in TESB, it takes more than a few seconds to take effect).

Vader’s able to kill someone with Force Choke from thousands of miles away. You think that he wouldn’t master the subtelty of knocking someone out via Force Choking?

Also in Lords of The Sith he choked out a main Twi’Lek character at the end of the book and in Revenge of The Sith he Force Choked Padme to unconsciousness.

Exactly, that’s what I mean. He initially thought he was “not as strong as the Emperor thought”, then, when he exceeded his expectations, maybe started testing him to see if he could be of some use to him.

I think he was trying seeking to use him anyway though his abilities showcased in the early stages of the duel only furthered him wanting to test Luke. But he was still trying to freeze him at first and that could have been done by much simpler means. He also could have picked him up, held him down with The Force and froze him that way.

When I saw TFA, I got from the beginning he was just some dude who was constantly being harrassed by almost anyone in that movie (from Poe to Hux)

And as you said before, just like Vader in STAR WARS. Someone we both consider a great villain.

who can’t take control of the situation,

Fair enough I guess.

certain he would’ve never harmed any of the main characters. And I remember finding this boring, that’s it

^ I’m sure this pleasantly surprised you.
