The summoner spell clairvoyance has great utility on this map and having one person take it can be a life saver as you can spot things on the map and the area affected is almost as large as an entire side of the jungle if case on the alter.
The new lantern Item reveals invisible units such as teemo and teemo shrooms, shaco and jack-in-the-boxes making it a great item and a good reason to have someone clearing jungle and helping lanes.
Teemos really good because with those two bruisers they can take control of the jungle real easy. The start from one end and teemo works his way up through the jungle laying mushrooms while his two bruisers baby sit him and he can book it to safety. And some bruisers like Volibear or udyr can also make a get-a-way real quick with their abilities.
you can use clairvoyence, but then you're forcing someone (or 2 people) to sacrifice a summoner spell to use another summoner spell that won't gel well with their champion.
you can get an active item but those have a cool down and you have to buy them and they need to be in close range to use. So notonly do you have to use it close range there actually has to be something there. That way you have to go real up close to a bush/area hope there's something there and praying the enemy isn't there either (such as rengar) and hope when you use the item that something is there.
Lets also not forget that the enemy team will no where you are this whole time because you're beating up their mushroom/trap whatever.
