Teemo changes

As dedicated Satanic I was browsing he teemo changes and the change to the passive I could not be more happy about it sounds like a really fun and new way to make his passive work for now I can stealth camp them enemy jungle brushes and be able to dodge the skill shots too. Now for his mushrooms. as we all know this is teemo's identity and it is being changed. With how the game has been progressing I can se why this change is being put in place. Champions are become more interactive as a rule and I believe that this is what Riot is trying to do with the teemo changes if you look at the new champs coming out they all see really fun because of the fun interactions they have and while it is not as bad as taric (poor soul) teemo was a bit interactionless. I know this will alter his play style a bit but I just had concern for one thing...5 minute shroom life....that's a pretty big hit now I am sure we can argue that 10 might have been a bit extreme with the fact most games last 30-40 minutes however I felt something like 7 minute life would be a bit more satisfying especially when as teemo you rely less on organized team fighting and more on guerrilla warfare and having the global presense of planting some shrooms in Mid lane then running back top to set up a minefield is something I feel like he needs and may not be able to do anymore Also is anyone had any thoughts on what when into the mind of why these changes specifically I would love to here them. My first thought was why didn't they change the e since it had plenty of room for innovation Keep calm and shroom on
