For me Personally i do max and evolve Void Spikes because i play him a very particular style like a slight of take of Diamond Prox (Gambit Gaming's Jungler) or if i feel good i evolve jump first (but still max spikes) and jump in and get the reset and straight out, it's more of a poke down then jump in kill and reset and get out because ever since the nerf he has lacked the insta burst potential unless super fed and you generally don't make it out, but my style is quite difficult and takes a lot of practice but i feel it's the best at the moment.Just my opinion, the slow and damage is really good as well as the nice heal, other than that i agree 100% with the build and i don't take the LS rune but its totally preference, sorry this is so long :(

p.s i have a few hundred kha games under my belt, only like 100 - 150 of the new one but still :/

I think you kinda need to evolve Taste Their Fear because you wont make Damage without it.

I see your point there. In my opinion I just see more benefits in maxing Taste Their Fear, because you max out your damage, you deal on ganks. It's not like you're gonna die in the jungle :P

Void Spike deals bonus damage against monsters, I think it would make sense to skill this one as early as possible.
