The meaning of a wall

Hello summoners

In some recent new champ kit (hello and ), we have see a new kind of wall totaly different from the older one ( , ) who are here to be a defensive spell against projectiles.

Their mechanics are also different from the other cause they only affect ennemi projectiles.

So, a wall who, by definition, must be a deffensive tool can be now turn into a powerfull harass ability with not so much conterplay except to run from where he is (difficult on some maps>-<)

Wouldn't that be better if, when the wall is cast, it remains till end of the spell or when an allied projectile go trough it? That will be more like the deffensive ability it is supposed to be

I don't know, maybe it's a bad suggestion for the health of the game but as we don't have much champ with that ability, maybe looking at it now is a good idea (not let it grow like heal or stealth and then change it because it's unhealthy^^)
