Focus an opponent that is away from his teammates and burst him down, preferably the AP or AD carry. After that stay alive and you've done your job, anything else is a bonus.

Your entire burst has an overall 8 second cooldown (taking into account buff, masteries CDR and synchronisation of abilities CD), once you burst an opponent, you can do nothing until the Q comes back. During that time, finish off anyone trying to leave the battle with a few HP left, it's your job to clean up, let the rest of the team focus and paralyse those who have some HP instead of running like idiots after the bruiser that has about 100HP remaining, that's why he snowballs so well: Kill securing with him is beneficial to the rest of the team. If there's no one fleeing, either your team lost, and you should save your skin/make sure the AD carry is dead so they can't push; or just E and W autoattack the one you just bursted so he can't participate in the fight.
