Huge Teemo and AP Shaco Nerf
With the change to Oracle Lens it completely nerfs both Shaco and Teemo. Most Invisible champions have a better chance to get away from danger now due to the change, but it completely nerfs Shaco boxes and Teemo strooms. My suggestion would be to bring back the old Oracle lens as another trinket with its old effect, but keeping the current one to do it's current effects minus showing traps. I think people would still buy both just in different situations. A big dilemma people face at the moment is not having a slot for pinkwards in the late game for invisible champions like vayne, eve, shaco, rengar and are forced to only use aoe's to kill them or stop them. Bringing back the old Oracle lens will give people the choice of buying the new item for clearing wards in aoe's around them, showing champions in aoes around them without completely revealing them, or buying the old item for showing invisible champs and verus traps when needed. I am incredibly biased on this subject because it is a huge nerf to my playstlye, but I also think it's a reasonable change/addition.
is a nerf towards stealth champions counterplay. It won't reveal them anymore so even if you see the red. This won't prevent them from killing you. This makes stealth champions stronger against it. This mostly effects the verry lategame when their is no room anymore for pink wards.
is a buff towards stealth champions counterplay. The cheaper pinks allows to counter these champions in the midgame

are the ones that will get reworked add some point.
