pros:
great spell vamp
deals massive burst damage
low CD
farms very well
better mobility

cons:
squishier then most vlads

Simple just ult on a team fight death-fire the person with the most health and then spam your E and Q moves (the CD will be sub 3 seconds) After every ability auto attack as much as possible to get the full amount of damage from your lich bane. You will be able burst down people faster then ever before. P.S. Don't pool into the team fight after your ult you will be targeted and taken down fast, only use the pool when escaping with this build.
