You have no feeling of distance...and I think its a bad usage of doodads. just spaming arround and there is to less space for battles...not good. Bad creep usage and bad drops
and the guy who told you to use high/lower ground is better than cliffs is just a noob...do not listen to him
ok the best thing to use is the high/lower ground combined with blizzard cliffs or just high/lower. It is the noobs way to just use blizzard cliffs. it looks awefull and you cant make both good looking and good to play hills and rivers. Grave digger just do what you like but try using high/lower it looks awesome.
