The Vampire ult deals about 200 damage per second to everyone in the area, meaning 1000 total over the 5 seconds. Lets assume 20% crit added (1200 damage over 5sec). Add spell resist and health regen and it'd still take MORE THAN TEN SECONDS TO KILL EVEN A LEVEL 10 PLAYER.
Like i've said before, if you don't react to that and just stand in crap, you deserve to die.
