Laxus had trouble with Wall before he succumbed to the Anti Magic Particle poisoning and was only able to win with a different Lightning that also increases his strength with the damage he has.
Wall immune to every Laxus attack how would he fought against him?
And Wall weakest among 12 spriggans
Red lighting ignored lighting immune
That's why king of the lighting Kirin took damage from this attack
Laxus early destroy sand storm from Ajeel and later almost kill Ajeel with lightning bolt as August stated and Ajeel only at one rank weaker than Brandish
Its similar to Sister Signario who counter Natsu FDKM attack but later he could fought against them even in base
