Teemo Suggestion: Scout Swiftly

Teemo has been hurt with how the recent vision update crippled his traps with no sign of any boost elsewhere in his kit. My idea is to give the active of Move Quick Scout Swiftly a minor scouting tool. This scouting tool would show footprints of enemy Champions in Teemo's line of sight. The idea here is that this would further fulfill Teemo's identity as a scout, give him a tool for staying alive when going out to set traps, and allow for a unique way to avoid ambushes. Furthermore, Noxious Traps could trigger this so that Teemo can track his wounded prey. If desired, the ability to also determine the direction that an enemy Flashes, which could give Teemo a nice little niche.

As time goes on the footprints would fade, so Teemo has some idea if the footprints are recent, plus it keeps the map from becoming filled with footprints.

Edit: The lightning bolt is an attempt to show how Flash direction could be revealed (plus I wanted to use the lightning bolt shape). Pardon my paint skills.

Edit 2: There is a concern that Teemo will gain too much extra power with this idea. To be clear, this is not a passive. Scout's Sight is like Quinn's Heightened Senses in that it is an active ability that reveals information. Since it only reveals footprints if an enemy has walked past the area somewhat recently, it cannot be used to determine if an enemy is approaching. Compound this with how Scout's Sight is tied to Teemo's only escape, the movement speed bonus, Teemo must choose whether to save the movement speed to escape or use Scout's Sight to see if an enemy just waked past the area. Choices like these don't only offer new opportunities for Teemo, but also for Teemo's opponents. A low level Teemo player might pop Scout's Sight anytime he goes to place traps, but a high level Teemo player would wait until she is more confident the enemy team is not 5-man stacked just around the corner in fog of war before wasting her only escape.
