Thanks for the reply Kurasami, -I don't opt for the teleport talent in the first tier because both of its benefits require you to be out of combat in the first place. However, i can see it's applications in avoiding ganks and getting away from approaching characters such as zeratul. I'll add a section discussing the benefits of taking it -My second recommended build takes the damage talent for teleport -Basic damage for missiles is worth noting and i'll add it to my talents section...

I really appreciate your constructive response, and I'm glad your enjoying the build. I've noticed it too, quite frequently I feel like it should go off more often, it seems to only really go off when the outside edge of the explosion hits an enemy hero at absolute max range. My bet is Triumvirate is going to be the skill cap choice; you'll prefer it when your consistently hitting those long range arcane orb snipes, something I'm still working on. I'm actually going to upload a video when...

Personally I feel like the build has plenty of damage even without it, you simply give up too much health for the boost. The build centers around having a reliable escape because Li-Ming simply can't take being focused. Taking the talent will only get you killed faster, and taking it means you give up Illusionist. I've escaped so many times with a a tiny fraction of health because of Illusionist both because it helped me escape and frankly Glass Cannon would of meant i was dead.
