Nexus Speculation

Recently I've started to get a feeling that Nexuses are overrated as fuck, so I decided to make a thread regarding their amps.

The most basic way a nexus seems to amp people is a passive amp. A force wielder may not be actively drawing from it, but they receive a boost in their abilities from being around so much energy. Basically a character's abilities may be amped to some extent, but it's not too far beyond what they are normally capable of.
Examples of this would be: Bane on Lehon, Bane on Ambria, Savage and Maul on Phleem, and Dooku on Vjun.

Another way a nexus increases one's power is when they are actively drawing on it. This significantly increases their abilities and allows them to do feats that are normally beyond them.
Examples of this would be: Bane's death field on Prakith, Zannah's tendrils on Ambria, and Vectivus's phantoms on the habitat.

Another way a nexus could amp somebody is if they have a natural relationship with the Nexus. A relationship with said nexus would increase one's powers by a significant amount and give them an edge over others. Basically for some, drawing on a nexus becomes a second nature to them due to their intrinsic connection with said nexus.
Examples of this would be: Vitiate on Dromuund Kaas, Nightsisters on Dathomir, Sion and Nihilus on Malachor, and Sidious on Byss.

This is my understanding of how Nexuses amp people.

Well now... backing up by claim that the passive effects of Nexuses don't amount to very much in the long run.

1. Darth Bane achieves the exact same speed on Korriban and Lehon, despite the fact that he improved from Korriban to Lehon, the fact that his fight here was more difficult, and most importantly that Lehon was far stronger in the dark side than Korriban. The nexus doesn't appear to be doing anything for Bane's speed here.

2. Dooku's fight with Yoda on Vjun isn't really that much more impressive than his fight with Yoda on Geonosis. They fight, neither hits eachother, and they levitate some shit. Despite the fact that this would have twice the net impact of a Nexus (because Yoda's supposedly being weakened by it as well as Dooku gaining strength), it really doesn't seem to amount to very much

3. The Kun discrepancy. Kun wields ancient sith artifacts and is highly familiar with Sith Sorcery. This means that the Artifacts or Kun could've been actively been drawing on the nexus's energy. There's also the possibility that Kun didn't fully intend to kill Keto, Kun didn't have time to charge a blast because he had to deal with Droma immediately after, or Keto's own abilities allowed her to reduce or absorb most of the damage.

4. Bane's collapse of the Temple of the Ancients on Lehon. In Rule of Two, Bane arguably achieves greater by disintegrating a dozen technobeasts. In Dynasty of Evil, Bane is never presented an opportunity to do something like this. When he's assaulted inside of his mansion, he is inside of the structure, so collapsing his own house on himself wouldn't really make any sense at all, and he was dealing with Cognus's force suppression at the time. In the Stone Prison, he was drugged, didn't want to hit the explosives in the wall, and was trying to keep his position a secret from Zannah.

5. Bane, who frequently notices when something is impacting his power, never says shit about a nexus making him stronger, except for when he is actively drawing on it.

unless the person is actively drawing on the nexus, the amp is so insignificant its hardly worth mention. Nexus's are just something people like to pull out of there asses when there loosing an argument, "Okay, well... He only did that on a nexus!"
