Tip overview

Vatu needs to come close to your teammates to deal signifant damage, so if you are playing cripple always keep an eye on them and cripple him as soon as he dives

try to predict where he'll land, if you can cripple him he's a free kill with your combo

Life Exchange - Use illusions to block shots, keep distance. When you can use another illusion to teleport away. If you have ult use it and teleport to a teammate.

If you had to iceblock in a duel and the enemy is very low, the fastest action you can do coming out of iceblock is actually to primary fire, almost all the other abilities have a slight delay. You might die, but you might not, and they WILL die.

I find blinking out of iceblock to have more of a delay than soaring out of iceblock, but soaring is easier to shoot. It really depends on where you are, who is looking to end you. Not staying for the full 3seconds CAN mislead the enemy too.
