Disruptor is a ranged intelligence support hero. Although picked sparingly, he has a tremendous capacity to control enemy heroes during teamfights and ganks, which makes him a fantastic pick-up in certain line-ups.
Skills
Thunderstrike is usually skilled and maxed first.
Glimpse is usually maxed second, although sometimes it will be maxed last.
Kinetic Field is usually maxed last, however it is sometimes prioritised second in order to get the full effect out of his ultimate.
Static Storm is always skilled (levels 6, 11 and 16).
Typical Ganking Combo: Glimpse > Kinetic Field (at return location) > Static Storm.
