Fixing Lee Sin's mobility outside of Summoners Rift

As a lot of you know, Lee Sin is the most talked about champion in the game, people calling for nerfs, fixes, balances etc....People seem to forget about his safeguard mechanic to wards, his main tool, the main reason people pick him. Outside of summoners rift Lee Sin is mediocre at best and needs something else. My suggestion? In the ward slot, outside of summoners rift, give him a item that he can either upgrade into, or have basic 'trap' wards that do nothing besides allowing Lee Sin to safeguard too it. This 'trap' will not grant vision outside of summoners rift and will act like a Caitlyn trap in the bush, it's just there. Allow this 'trap' to disappear after a certain time so that Lee Sin can use this to safe guard to this 'trap' and allow himself to kick the enemy into his team. This trap would also replenish over time or when Lee Sin goes back to the fountain (for ARAM it would regenerate over time and Dominion/TT would replenish on recalling to the fountain).

Thoughts?
