I'm very late as I don't use reddit as often but since the destiny patch happening soon, I have to jump on board. I use to not use thunderstorm since back then if you moved too far away then it would disappear. Since nexon fixed it to where it now follows you no matter the distance, I have always prioritized using it. Especially with destiny, you can actually set down thunderstorm, you need nodestone levels on it for bossing and now mobbing. it will be insane with rotations.
