ward vision issues

Two things. First has been bugging me for a very long time, second I randomly found and would like to mention.

I like to use the quick cast for my items and trinkets. I understand that if you don't quick cast, you can tell if the ward will be in a bush because the cursor is green. I think that, this feature should be updated so that the cursor itself is green tinted if it's in a bush. there are too many times when I think a ward will be in a bush, but it just isn't in it.... it's behind the bush instead... and sometimes, you don't notice that the bush isn't fully visible, because when you have vision near a bush some of it lights up and this isn't enough "not lit" compared to a bush with vision that you think it is the "vision light effect"

TLDR because of 3D rendering and lighting, sometimes you ward behind a bush and don't know it 'til an enemy jumps at you...

the second, on the bot lane wall behind the outer turret, there's a little nub that blocks vision if you ward over the wall. you can't see this nub from lower angles, because there's a fancy tree on top of the wall that "hides" this bump, and the wall looks like it is flat. I've placed a ward there, and then a ward in that little bush next to the krugs, and had to battle with a thresh I couldn't see because he was just out of vision of both wards. and, I actually at the placing of the ward, thought "yeah this spot will reveal him" because it looked from my angle that the wall was linear without a bump. I don't mind if that bump is intended for this sort of thing, but if the bump remains it needs to be more visible.... like, to remove the tree for example, to make sure it is seen when from an angle...

sorry for lack of screen shots. for some reason I can't take them when League is in full screen...
