Reading from "welcome-to-dota-you-suck" guide
I found the bolded part at the bottom particularly interesting, me being a noob. I always auto-attacked the creep line.
I tend to auto attack creeps and push the creep line back toward their tower. And I do tend to get ganked on their side much more frequently than on my side. So I am thinking about adopting this. I mostly play support classes for what that is worth.
Thoughts?
Adopting this (at least in early game) is absolutely mandatory if you want to farm without getting ganked.
Don't auto-attack. When it comes to creeps, only attack to last-hit or deny.
