Not trying to start argument .. but I think u r overeating luffy .. a bit Idk where article is but Op is supposed to b for another ten years luffy cannot b tht close to admiral level already it's 2 early ... Admirals r marine strongest fighters
Also zoro is suppose to b almost as strong as luffy r u implying the 2 of them would Gove admiral high diff??? Cuz I think not
Luffy intends to take on Yonkos after this, even if its going to take a 3 on 1 Luffy by that time should be comparable to a Yonko FM, especially if Zoros going to be the one that beats Kaidos FM.
Luffy at this point in time should be strong enough to hold his own with an admiral but still lose, the training was a complete waste if they can even one shot him in Gear 4. Give them mid dif or something at this point would be my guess.
Also at this point theres 9 years to go and that depends on if Oda actually keeps that promise, he may change his mind and make it shorter you never know or be told to pick up the pace.
