I dont know why you are ranking wahl so high. He is an average springgan with average states for springgans. I am not gonna hype him up for some aoe or name like etherion. Wahl strongest move is etherion, invel is his ice armor. Wahl etherion is simple blast like attack, ice armor super cold defense. They are equal in strength so they should technically cancel each other out. Laxus has no power feat of overpowering a springgan strongest move, gray has.
I will give you that the armor might be more towards freezing then defense, but it is an armor, gray overpowered its freezing ability and its defense, gray overpowered it completely.
Invel body durability should be equal to wahl body durability. His armor is extra defense.
Seriously, i dont think there is any point in discussing this further. I simply dont believe wahl can have offence above invel defence. They are average springgans so their stats shouldn't be that out of wack
Seriously using gmg cards

Fine, i will agree with them for you.
Now keep in mind those gmg cards shows stats of laxus after time skip training and stats of erza before SO
So basically stats of gmg laxus and pre time skip erza

And and Natsu and sting and rougue were all equal
Hyping the enemy, like that is the first time we saw bs hype like this. Meanwhile without SO erza took out a pre ts jura tier monster plus 99 more monsters. Jura was suprised by that war god spell as well.
August was wrong. It did nothing to ajeel god complex, beside casual laxus killing springgan means he is aconologia tier, which is also bs. Stop believing every laxus hype. Or atleast believe all hype then. Laxus can mid diff ajeel, because ajeel hax wont work on laxus
Yes, erza needs help protecting the orb. Not defeating laxus. Laxus and erza are about equal. Erza interest is only in protecting the orb.
He beat kyria because he is weak

Its interesting that people actually believe difference between natsu and erza is small and difference between laxus and erza is huge. Even though before the time skip there were so many direct or indirect comparisons between erza and natsu but zero between laxus and erza
Aria low diffing natsu comparef to wrecked erza one shotting full powered aria, OS first appearance (natsu, gray and three fodder lost to racer, and racer plus cobra plus his snake plus sneak attack from hoteye put erza out) and azuma causally one shotting pantherlily just after edolas arc where pantherlily stalemated gajeel.
Erza had hype and feats above natsu pre ts. Laxus had nothing, not even hype. So no makarov doesnt think laxus is stronger than erza, nor does gildarts think that nor does natsu. If misham doesnt interrupt this fight, we will have our answer and you can lord over me how laxus one shotted erza
