As title says... This to work in conjunction with the new support vision item, wriggles and the new vision granting items.

The wards from items are standard non vision wards, and pink wards would cost maybe 90-100? Need tweaking im sure but oracles is a fun killer.

The main reason this would be a disaster is because you would constantly be putting up pink wards and killing other peoples pink wards. It would change the gameplay drastically as players would start to engage in ward wars constantly trying to kill each others wards in the river.

This would end up favoring the bottom left teams top and the top right teams adc/support lane as the bushes would give them an advantage in this war.

You could change your idea to keep the price of pink wards but I think you won't convince people they wont need wards which will just force the support into spending more money to do what they already are doing now, which would effectively just make them even more poor than they are now which is very poor!(Ward wars would compound this problem even if you lower the price)

Oracles isn't a fun killer. Stealth was the fun killer. Riot even said so and they revamped long term stealth. Eve is the only one that still has some sort of long term stealth but she's revealed when she's close to you.

you make good and valid points.
Wat do u think then about increasing the cost of pink wards but making them invincible? you might be able to see it there but cant destroy it.
They are adding items with grant vision in an area on approx a 1 min cd. This will let u get rid of the normal wards created from items like sight stone and wriggles. or u could pink ward at a hefty price,= (maybe 200-250) and have 3 mins of guaranteed vision?

in addition maybe change clairvoyance to be a sort of magical ward that cannot be destroyed, that might last for 45 sec or something but have a 3 min cd?
Its not that i dont think oracles is balanced, that isnt my prob with it. it just doesnt promote strategy/skillful play. it is a u need it for most of the game kinda thing.
