Laxus had more than Lightning, he had brute strength Which Wall could tank in base,
You’re a clown who just wants to troll with controversial opinions. Laxus struggled with Wahl only because of MBP sickness. And he didn’t need Third Origin and slayer advantage to finish Wahl with Red Lightning.
Laxus stated that it doesn’t affect him until he has episodes. Wall even reinforced this that despite being afflicted with particles, he still operates at the top of his guild. Red Lightning already augments his power with the damage he took and he struggled with the weakest in the tier. While Chelia did win, had some help and slayer advantage. Still strength is a factor.
It DID affected him, if you see the fight with true eyes and not by your Spriggan fanboy braindead, Laxus was slowed down many times because of MBP. Yes he is at the top of his guild even with his sickness, doesn’t change the fact that he was highly disavandtaged. There is a reason why Laxus finally won after he was cured, because without particules, he would clearly crush Wahl and many of the Spriggans. But you will never admit it, because you love way too much your Trash Spriggan to downplay them.
Yes after Wall transformed, not before, it does as it didn’t hamper him before he struggled. He won from a massive powerup via red lightning. He clearly couldn’t as he was just shy above Erza level and she struggled with berserk soldiers who are weaker than Spriggans. they don’t beat the DGs at their max, that is clear, but they can still harm/affect them that is the point.
