Its not only that old visage was boring to alot players (hey, I actually liked him aswell a couple of other people also did but the majority didnt) but also that he was lame in a competitive game. tonns of flying observer wards that also made lasthitting and pushing incredibly easy and a hero that after solo ricing the entire early/midgame was able to carry, tank and also make sure your allys do not die.
the new one is a completely diffrent hero in almost all aspects. main diffrence would be: dont even try to farm with the hero because he is very bad at it. he isnt a full carry like he used to be.

and I liked New Visage the way it is, just that I don't really like the insanely high APM that it requires. Stone form, attack with Visage, attack with Gargoyle, spam nuke, spam Grave Chill, careful of Gargoyle dying, careful of yourself dying. Too many things at once need to be done.

and the only thing i just hate about visage (both new and old) is his goddamn attack. It takes 1 second for him to decide who to attack , why to attack , how to attack and when to attack , then 1 second to pull his tail up , 1 second to rethink his action , and finally, one more second to throw a purple ball which goes slower than techies without boots
