First i want to say, awesome guide m8, i've been a long time Gazlowe player and i feel your guide is spot on, there's only 1 thing i would like to add, the lazer build is more than viable now, i don't know about in hero league, but atleast in quick match, i've been topping hero dmg most games with it. I feel that gazlowes teamfight potential is very lacking without a way to focus people, since his turret's aren't reliable without the robo gob at lvl 10 for focus fire. so the lazer build is awesome to get that morales/chromie on the backline. Also the lvl 13 freeze talent really excels at clearing enemy mercinary camps on lanes, and also give your own a breather form tower/fort fire, potentially saving them 3 sec's of health - sorry for the wall of text :P, gj

"If you are building the Deth Lazor, this is the top talent for that built."
And still your not implementing it in your own build....
