So assuming semc figures out a way to fix the current issues with meta, so they find a way to make laners actually have to farm their lane and go trough a lanning phase instead of spending most of their time sharing jungle ambient. And they figure out a fix that allows junglers to be anywhere on the map instead of hovering bot lane, the meta will still be extremely unbalanced. Reason ? The map mirroring , it means that a bot laner typically a weapon carry has to play a lannig phase against a top laner typically tank that builds utility. Regardless of how they balance the heroes and items the meta will be unbalanced and here is why:
The heroes that are played in top such as Cath, Ardan, Grump etc… they’re all heroes that are extremely tanky that have a lot of utility and with high base damage. In a scenario where nothing is touched so with the current heroes and items balancing), there is no way a bot laner wins a straight 1v1 against a top laner the only heroes that would be capable of doing so are probably kensei and kenetic but that would be after they completed mask bp and a block.
On the other hand in a scenario where top laners are nerfed or their core items such as pulsweave gets nerfed then it would be the bot laners that would have an absolute field day and bully top laners due their range and mobility advantage.
Either way i don’t think a sweet spot can be found where a fair lanning phase can be played because at the end of the day its two very different categories of heroes going heads up. Another issue that a lanning phase in the sidelanes will generate is the mind games that will happen during draft, you think x hero for the enemies is going bot so you pick y who counters x and go top but then the enemy pick z who happens to counter y and z is the one who will actually go bot for the enemy. Drafting becomes a chess game where both sides try to bait picks in the sidelanes and basically pick a counter for the counter for counter for the counter of the counter… it never ends.
If semc wants to create a meta with a lanning phase in the sidelane then they would have to remove the mirroring which i believe is not possible due to how the game’s engine works (could be wrong tho don’t quote me on that). But if it is true then the 5v5 meta is forever doomed in my opinion.
