I think they do need to compensate him in some way because before trackers knife was in the game Lee sin actually bought sight stone. Now he cant buy that OR trackers knife as they have both been removed.
I hope that they introduce a new warding item into the that doesnt require a whole Quest to complete.
Or you know....... bring sight stone back
They could make it so its a tradeoff. you either get the support item and all the other stuff. Or you can get an improved Ruby Sightstone.
This way there is a tradeoff and a way for champs who arent supports to actually get ahold of a warding item.
