I have survived many Division 1 Games with this build.
<Enhanced Agility> for your only talent that gives you movement speed with this build. Then, to be successful you must pick <Hero Stalker> and kill heroes. Winning team fights is priority, especially with Dehaka.
<Symbiosis> and <Whirling Dervish> go perfect together. <Isolation> is a very popular pick over <Adaptation>.
I personally prefer <Elongated Tongue> over <Paralyzing Enzymes>. And Apex Predator is very important for getting in and out of places with a very short cool down. This ability is amazing for retreating, it is almost an instant teleport. This is a must.
