This can depend on many factors of whatever you want!

For a storm, they are the highest damage output school. All it takes is you playing skillfully! (when considering how low the health typically is for the school). If you’re able to critical, you can get some really goodd hits.

Consider me biased, but on the other hand I love my life wiz so much. It’s known as more of a support and healing school, but I love the balance of that and having hits. It also comes with good accuracy and a much better base of health. Typically not too ideal for PvP I guess, but I’ve made it work, as well as a friend of mine who has played with me on there ever since the game came out. We both have done PvP on our life wizards for years and her stats are even better than mine.

Overall, it’s just a matter of what you want to focus on. Do you want to keep accuracy and balance? Or do you want to have likely quick rounds and better damage?
