Why is Steel Wing + Dragon Pulse the strongest defensive moveset on Dragonite when it is so easily dodgeable?

As reported elsewhere "this dodge window to be approximately 250-400 milliseconds after the yellow flash regardless of the attack. All that matters is the yellow flash."

It means that the dodge window is the same for all attacks, charged and fast, and the damage taken if dodged is always 25% of the undodged attack.

Therefore the recommended defensive moveset makes perfectly sense.

Exactly what R_canine said. I don't understand how people consider some moves to be easier and some to be harder to dodge. Personally, I don't really see a difference. What do you mean harder to dodge? Do you mean that the yellow flash happens earlier in the animation or what? By now people should be pretty familiar with most moves anyway.

I think steal wing is just as good as dragon breath. Although dragon breath does less damage but harder to insert more moves between dodge due to lower CD.

Dodge window are the same for any moves. I did tests before.
