Me personally, I want to see lanes change around;
While I know the Meta will always be core around Solo top, mage/assassins mid, cc junglers and support/adc bot lane.
I want to see things like Mage/Supports bot with Marksmen mid or top, just to increase champion diversity. While I know I CAN take my Draven midlane. It's not viable and would be considered troll by most people.

Illâoi Evê Siôn4 votesI would like to see Marksmen get a solo-lane bot, and Mid-Laners getting paired up with Supports.
A lot of Marksmen could pull this off with the new Essence Reaver (sustain + CDS for survivability), or champions like Cait can just huddle up around the tower to protect themselves.
Edit: The duo lane would be mid to obtain higher objective control (Rift Herald, Drake, etc.)

Definitely, I think Mage/Support combos could be amazing.

I would like to see something similar to that also, or more of a roaming support meta as vision is now just as important top side because of the additional objective. I already roam often as support trying to get deep vision and picks in mid lane, but I can see supports going with the jungler for first clear and then making their way to either of the 3 lanes.
xJLx MCHammer2 votesI want to see what adc will go mid and top
Personally, I think graces, quin, vayne, and kindred can and will be top
Mid will see cait and corki a lot more.
Hayaishi21 votesCait is gonna be cancer.
Top Lane Terry1 votesNo more tank meta. And I think everyone will agree.

FakeGravity1 votesSivir mid is actually very strong with both the ability to push and the safety safety from spellshield Also remember varus and ezreal being use there for top expect new graves Caytlin and vayne that should leave a lot of space to play around and have mages and tanks all around
Meep Man1 votesA meta shift to a Role Neutral Meta
RedCyclone1 votesI really want tank supports to die down Every game is Thresh/Blitz/Braum
BottleCapster1 votesthat's probably not going to happen, as it stands tank supports are going to be able to get a pretty much permanent 8% damage reduction and eat some of the damage for their carries. Braum and the other tank supports will be really strong, and combined with the other new AD defensive items, should be ideal for keeping carries alive.
Transgressor1 votesI want to see a meta where ADCs are no longer part. I want to see a meta where solo tanks braul mid, instead of AP/AD carries. I want to see a meta with double junglers, 1 for blue and 1 for red. I want to see a meta where supports duke it out solo top, get gold, items and shit, and then bring their utility full force down the map. I want to see a meta where immobile mages and supports fight bot 2vs2. Imagine the area control from all the mages and the utility from supports backing them up, oh what an entertaining fuckfest :D
