I'm under agree that if you have speed and are weak you can still be strong Because u can dodge at ese so you won't get hit and you can attack fast. As if you had strength you are usaslly are slow so you would be and esay target for a fast person.
If you have a lot a speed and are weak, that doesnt mean you have strength. That means (like u said) that speed can dodge quicker, but, you cant deflect strong attacks. With strength, you can take down the weak speed type easier, but not in a short amount of time. Speed doesnt = strength.
Just because you are an easy target if your a strong type doesnt mean you can be taken out easier. EX: Youre a strong type of character. A speed type comes to strike at u, but you can deflect the weak attack, and throw a strong blow at the speed.
