For Disruptor, his most important ability is Glimpse. You can get early kills by spotting heroes that are out of position. Remember that glimpse will teleport back the enemy after 4 seconds so when you see an out of position enemy that is running back, count to 4 and cast glimpse. If you paired this with Smoke of deceit (100 gold that lets you stay hidden even in the minimap and increases your movespeed as long as you dont get too close to enemy heroes), you can get some sweet first bloods on the enemy middle players (just remember to coordinate with your own mid player too). The first skill Thunder Strike is a skill that grants you vision of an enemy (very useful so you can land Glimpse even if they are hiding on trees or fog) and damages them every interval. Don't hesitate to use your ultimate even if it's just 1 hero (especially if it's the enemy carry). One good combo will be to glimpse the enemy, then start casting Kinetic Field and then cast your ultimate skill. Good items for Disruptor are Urn of Shadows (heals overtime if used on friendly units while damages over time if used on enemy units), Force Staff (more int and good item for positioning), Aghanims Scepter (enemy heroes will not be able to use their items when you land your ult, very good for cores with BKB). Last but not the least, at all times plant observer wards for your team. Also, always carry a TP, when you see an ally being dived on your own tower, teleport immediately for a possible turnaround.
