you are the most retarded user I've ever seen
don't want to accuse you with this
it's just a matter of fact
topic:
lowering/raising terrain won't influence the vision
in maps like dota visibility plays a great role so you should consider cliffs
other options would be a triggered vision (more flexible but more complicated; there is a sample of it in the jass section) or vision blockers (two-sided, so units can't look down from the hills)
