Well its strengths are
its cutting power its versatility and supplemental uses its powerful against earth and can be used in combination with water it can be used as short mid and long range projectiles spears senbon it can be infused into weaponry to charge them increasing there cutting power as displayed by such users as the 3rd and fourth raikage kakashi sasuke darui killer bee and so on all in all its a powerful explosive element and works best with fast techniques and sword users
@Bolded part is totaly wrong.
The Lightning doesn't have a cutting power. This is Raiton we are talking about not Wind. Fuuton is the element that has a cutting ability. Versatility? I would again not agree because this is about wind once again. And supplemental uses? This is an offensive element not supplementary one. Go in the jutsu list and find me more than 2-3 supplementary jutsus.
Lightning an element with incredible potency, an element that can burst through fire, destroy earth, electrocute water. It brings destruction wherever it goes. Lightning is an element of pure destruction, unlike the four other elements that come together to create the basis of life, lightning is the opposite. It is pure death.
Didn't get why the element works best with sword users? Raikage isn't a sword user but is one of the most powerful Raiton users no?
Any questions so far?
