I'm both surprised and confused by this statement.
Historically, Riot has been extremely aggressive about nerfing champions who seek new lanes or jungle.
Alistar jungle, Lulu top, Karma mid/top have all been nerfed out of the stratosphere. The nerfs were deliberate and drastic.
Does this mean these champs are going to be reworked, or their nerfs undone?
Yeah, I can understand how that seems a little confusing.
When a new playstyle emerges our goal is never to shut it down immediately, but rather evaluate and see if it's healthy for the game. Over time, that means that we've nerfed some unhealthy playstyles rather than trying to find a way to make them healthier.
The difference now, I think, is that we're actively seeking out more opportunities for champions to branch out into other positions, and see if we can support those more. So we're prioritizing those opportunities with the goal of opening up some healthy alternative playstyles.
The problem is that picks like Lulu mid or Fizz top only worked because they were overpowered
when a champion plays into a new lane riot doesn't nerf it immediatly
However when the new playstyle is unhealthy as fuck then yes they do and make it unviable
Alistar jungle was: aids cancer overpowered as fuck unbalanceable
his ganks had no counterplay, his clearing was fine, and there were no reasons to pick an other jungler into him after he hit lvl 2 he could walk everywhere and get free kills everywhere without the enemy able to do anything
after lvl 6, if you cc'ed him he could remove the cc walk to you for a kill, and even towerdive
Guess who hasn't been touched ? Vayne top Lucian mid Twitch jungle
I wonder to which class do they belong to...
Let's not buff lulu
As a support 
main I'm happy to see Riot taking this direction.
I personally think her kit is already good support, all she is missing is a better manapool to be reliable on the role.
mid: 
top: 
jg: 
i dont exactly see the issue here
