Imo, Snitch could have its range reduced (800?) and cost increased (- but come in two charges where the first is destroyed and the item is consumed when the second ward is placed. The decreased range makes it easier to play around for the enemy once they know it's there - given the range and the visible/audible ping for allies, it basically makes all gank attempts impossible even to those with bad map awareness. The increased cost is for the two-charge system, which is because then its user can add a second ward if the enemy jungler figures out where it is and changes their gank route to get around it without causing the ping, but limiting it to only one of these placed at a time so it doesn't just end up where it was before (making a lane un-gankable until the ward ends).
