Namitaro's hook rate is actually pretty ridiculously high during that one-minute buff, though. I think I caught six Giant Takitaro before I landed Nami; of those six windows, I hooked Nami four times (three escaped, one caught). While admittedly a small sample size and I have no idea if I was just lucky, that's a one in three chance of hooking Namitaro while Fisher's Intuition is on. I don't think any other Legendary has anywhere close to so high a hook rate - and so, to balance that, SE made Giant Takitaro tough to catch.
