Oracle's Alteration too good for stomping teams

Nerfing Oracle's by atleast half it's duration (on top of the more obvious damage creep nerf and tower buffs that are needed) would help a little bit to prevent hypersnowballing stomps that are happening now.

Situation: 19 minute in your team is turtling at inhib turrets because their assassin 6000 HP got 3 kills so he's insanely fed in this meta and one shots your tank. Your team makes a difficult macro move, using to find their team in one quadrant of jungle, rushing 4 man to other side of jungle to ward everything up while one defends turret. You somehow only lose half a towers health, luckily. Now maybe you can use your vision to strategize your split push waveclear to what side enemy isn't and atleast attempt to defend effectively right? Nope. Shortly after their support uses a 60 sec CD trinket at no gold cost or risk to kill all the wards of an ENTIRE QUADRANT of the map you just put, with just their adc (probably a Yasuo) to help btw, denying the turtling team all vision on the map. No need to buy . Just one on one champion.

Meanwhile the rest of their team waveclears everything on the other side of map, takes your jg camps and bushcamps for insta-assasinations if your team DARES step foot past your walls. Now your turtling team just waits for them to take baron and end, or you walk into jg with no vision and probably get 0.05 second assassinated by a . Real fun the stomp or get stomped meta btw.

People don't actually think this hard anymore to startegize in solo queue btw including me. It usually goes more like

18 min. "crap one of our guys got caught out" 19 min. enemy team rips through 3 turrets and mid inhib 20 min. "can we contest baron?" 20 min. enemy team has slain the baron! 20 min. "Probably not" 20 min. "Report jg no ganks" 20 min. Your team has agreed to a surrender with 5 votes
