there aren't really too many heroes in Dota 2 with "builds." There might be certain distributions that work better than others, but pretty much anything goes. I guess you'd get made fun of for really strange things (like a passive that does absolutely nothing without other abilities as your first skill, like on Earthshaker or Zeus), but overall nobody cares the order of skills you get as long as you make them work well.
that's what i wanted to hear.
