I didn't say he can't control it, i said he hasn't perfected it completely. There's difference in both.
Hence i said, he won't collapse atleast not until he has done his part in the battle.
It is also expected some if not all of them will fall at some point during the fight. So it works out, especially if BM leaves the stage.
I think you completely missed my point..
Zoro can always redo DR feat, slightly better since his Haki control has also improved.
But Enma allows him to do much better when he wants it to.
That's why i showed Mihawk slash, Roger vs WB clash that DR slashes ain't Zoro's limit. Zoro still had to be launched at Pica to cut him, Mihawk slashed iceberg from miles away casually.
My point being The more haki you have on your swords/use in your attacks the better the attacks, and we saw the max Haki Zoro ever had was with Enma.
That's the advantage Enma provides, it also helps improve Zoro control over his swords and Haki.
Why not? Do he needs to fight Kaidou for days or to harm him/try to finish him in one go if he can?
Actually also tell me, if Enma only hinder Zoro why he is fighting with Enma right now then?
If all it's purpose was to better Zoro Haki control during the training that's been done, right?
Why didn't Oda trade his sword back after that training? Why didn't have him find Nidai Kitestu or temporarily borrow Shishui back? Oda could have easily done that.
Simple logic, if there's drawback there's also the benefit.
If Zoro currently has Enma despite the drawbacks and difficultlies, that's because he needs it and it will help him.
So No the comment isn't pointless. It highlights the importance of Enma over other swords in this Kaidou fight/the buildup feat.
If all 3 swords harm Kaidou, then i will agree yes the comment was pointless.
