Wind wall vs other champion terrains.
So was watching my friend play yasuo and he uses his wind wall on the kurgs to get vision on them so he can dash to them. I thought huh didnt know his wall granted him vision. So then that got me thinking why does yasuo's wind wall grant him vision but anivia wall and trundle pillar vision was taken away from them? Is it because you can use the wall/pillar from far away to act as a temporary ward? Or is it just the yasuo bias? idk
terrain can be put much further away and covers a larger area. It provided way too much safety on a lower cooldown.
create Terrain.
and
Create a safety zone for their allies that buff, heal or protect them.
Weaver's Wall,
Emperor's Divide. They grant vision too, but we can omit them the argument, I guess. They also displace units as well. I guess they must be hella OP since they can displace AND grant vision.
Wall of Pain grants vision too but is still allows enemies to pass through like Yasuo's Windwall.
chompers for instance. They took the vision off for a second but I made a stink and coincidentally they put it back on.
