Sadly no.
This was all the hype they got. Laxus mp was no where near brandish mp.
As for wahl. Laxus needed powerup as well. Which wahl provided him. And also alot of cis on wahl part.
So you need to factor that in as well
Says who? According to who is Laxus' MP < Brandish's?
The only direct comparison they made was to Makarov's MP, i.e to a Jura tier's MP
Gray shat his pants at Brandish's MP.
The best you can scale from this is Brandish's MP >> regular Gray's, which is fair. But Laxus >> regular Gray, so it doesn't prove anything. Same for FDKM Natsu or Jellal or Gildarts.
Gray himself low diff'd a Spriggan having stronger portrayal later (Zeref's right hand man), and stalemated END who overpowered Dimaria's hax and no diff'd her.
END = darkness Gray >>> Dimara/Brandish. In both MP and stats
Unless you believe Laxus is << darkness Gray, he scales.
Also, since we agree getting scared at someone's MP should suggest something about relative MP. We can then agree Jellal's MP >> Neinhart's since he shat his pants to Jellal powering up? Well, I expect you to find some excuse, but the portrayal here is self evident for anyone arguing in good faith
Laxus' MP ~ Jellal's MP >> Neinhart's MP ~ Brandish's MP
*************
Regarding Wahl, Laxus was nerfed with MBP, so at best the railgun made up for it.
And Wahl was immune to his element.
Sure, CIS was involved here with Wahl, so what? Laxus got an opponent immune to his offense, and the moment he bypassed the immunity, he one shotted him.
Laxus had the portrayal to one shot a Spriggan (yea, I'd take the words of wise August rather than arrogant Ajeel. At the very least it would've severely injured him, and a second nuke finished him off).
And one shotted another Spriggan.
The fact that Laxus was given an opponent immune to his element, on top of hism being sick in the fight, tells us all we need to know. Mashima need to nerf Laxus to give us an entertaining fight with an average Spriggan
