Non-Rift Trinket

It seems redundant to have so many items that grant vision on these maps and to be constantly having to adjust how attractive the items are (Hextech was over-performing when it was one of the best AP items, but now it's a meh tank item; and the alternative is a crit item)... why not just put the vision on a trinket?

Firstly:

• Madred's Razors removed. (As much as I love double-jungle-items in Twisted Treeline...)
• Grez's Spectral Lantern removed.
• The Lightbringer removed.
• Hextech Sweeper removed.
• Oracle's Extract removed.

New item:

• Soulsight Lens Availability: Howling Abyss and Twisted Treeline UNIQUE Active - Hunter's Sight: Reveals the target area for 5 seconds and grants persistent sight of enemies revealed for 3 seconds. (800 range, 375-AOE, 120 second cooldown). At level 9, Hunter's Sight gains the ability to detect stealth, the cooldown is reduced to 60 seconds and it can be upgraded in the store to Grez's Spectral Lantern.

• New Grez's Spectral Lantern (friend referral after all) Recipe: Soulsight Lens + 475g (this cost is a lever - increase it or decrease it depending on how annoying Teemo is) As above, but also grants UNIQUE Passive - Trap Detection. The active could also grant Oracle's for 10 seconds, as with Oracle's Lens (if necessary).
