It's brilliant for my team so I just go with it!

Answer 1

Lightningrod gives Pokémon immunity to all Electric-type attacks and raises the Pokémon's Special Attack by one stage whenever they are hit by one.

And that is very as it protects it from Electric-type Attacks leaving it with only one weakness

It's true - it have changed into an awesome ability!

Answer 2

I like apple pie :-)
I don't actually know!!
it isn't particularly strong so its not to give it a bad point.

maybe its so it can be paired with something weak to electric in a double battle as a support pokemon

hope I helped!! :-)
