Why is it intentional that not having sight of someone completely negates your rune choice? Sight or not, you should get the movespeed toward them.
Minor runes should generally be fairly low mindshare and if gameplay on AV is Ashe fishing over walls with W and checking her MS to see if someone's there its pretty weird gameplay. Theres also some consistency rules with stuff working when you see them and not when you don't.
Also a lot of cc reveals, tho certainly not all.
All that being said, it's a tossup because if you hit your morg bind while they dip into a bush you should feel good about it and benefit from your choices.
