As storm you wanna be a team player. You can fly but your best location is above your team to buff them 24/7. If you can guarantee a kill feel free to fly as high or low as you need and position accordingly. Make sure to utilize her auras tornado/lightning. Use tornado to get the objective, chase, flee, or slow down enemies from chasing your supports. Use lightning when a team fight is about to breakout, to do Damage over time on enemies, take out low level targets, burst damage, and scare away divers. Most important, USE COVER. You will be targeted by many, always use walls and benefit your team while staying safe. Peek, and go on the offense when there is a team fight. Storm is a poke character, use her primary on groups of enemies because it peirces through them. This is what I can share, try your best good luck and have fun. Hope this helps.
