Pathetic attempt to troll.
There are more than 5 in this one since.
If he was having problems Oda would have showed us because that's how he writes. The facts Oda told us the numbers suggest that how many Zoro will face. It's there way of telling Zoro they believe there are too many for him to beat. Remember, there are over 30,000 opponents there and Oda specifically told the number of Gifters. He did that for a reason.
In facts, the Gifters even asked Zoro to join Kaido's crew. That shows they recognize and acknowledge his strength and skill.
