If you exclude Ashura Zoro showed his best cards.
Ashura could have been used as a last resort to solve a situation where these cards don't work out.
So i have to disagree if someone says that he went "all out". Can't be "all" without Ashura.
I also disagree though with those scaling Zoro on the assumption that he showd like 30%, and he could actually casually walk around Ashura mode for a whole arc and wreck everything in his path.
One of the Zoro wankers dumbest takes post time skip is attempting to keep the equvalence between Luffy's Gear2/Gear3, Sanji's DJ and Zoro's Ashura to argue for how much strength he is actually holding back.
Based on how it was handled so far, Ashura is still in his pocket, but remains an ultimate Trump Card.
