i really dont care about teemo's shrooms.. but yeah the whole "getting rid of vision for pro play" is one of the most bullshit changes i have seen.
you also forgot to add
now 1 shots ward.
and that instead of getting sightstone at 6-8 min support now get it at 11-17 min, nearly twice as long
this absolutely absurd, even in PRO PLAY the map is dark, in normal play you are lucky yo have even 3 people on your team place a 
it is absolutely horrendous how dark the map is.. and as a jungler there isnt shit i can do about it anymore. i also cant even clear wards with
because i cant drop my
anymore..
does riot actaully think not having vision HELPS?
oh the pro's are playing to safe.. because damage is absurd and stepping out of position for a half second can get u one shot.. lets remove all vision so they have to play even safer.
whoever came up with that idea need to seriously re-evaluate their logic. no pro player is going to make stupid risky blind plays with damage as high as it is.
all removing vision is going to do is make game for them last longer.. and becuase normal players so stupid shit blind and most dont even properly ward in the first place. and those who do no longer have the tools to.
i have literally considering buying support items on my non support laners, just so i can ward.
it is absolutely stupid.
they are literally RUINING the game even more because they have some bullshit assumption it will make pro play better..
