The game changer
Use vault-breaker it start and or enter a team fight. it ignores creeps and only connects with champs so feel free to use them as cover until you're are ready. Follow up quickly with excessive-force it can be cast twice before CD and does more dmg after vault-breaker and all of the excessive-force hits count in the 3 hits for denting-blows. lastly assault-and-battery is a great way to follow or engage a new enemy if vault-breaker is on CD.
You wont be the Person you starts the team fight but played right you will be the one who cleans up. You have two ways to chase and an aoe spell with a 1 sec cool down. So let your carry do some dmg and the tank take some dmg then dive in with either dash and start focusing down their carries.
