Top
The top lane meta in League of Legends Classic features a strong mixture of lane bullies, scaling carries and champions that can influence fights across the map. 
Jax remains one of the strongest late game threats, while the newly added Fiora offers a dependable laning phase, reliable crowd control and strong all-in pressure with her Ultimate.
Nasus and 
Tryndamere remain powerful despite receiving nerfs this patch, although both should be easier to punish during the early game. Champions such as 
Wukong and 
Kayle can take over games when allowed to play around their strengths.
Jungle
The jungle meta continues to reward champions that can create early pressure while remaining useful later in the game. 
Lee Sin and 
Jarvan IV are still two of the strongest choices thanks to their reliable ganks, mobility and ability to set up fights, although Jarvan’s defensive scaling is slightly weaker following his nerfs.
Carry Jungler such as 
Master Yi and 
Evelynn remain dangerous when given enough time and resources to scale, which offers extra flexability/priority for players who like to power farm.
Mid
Mid lane remains one of the most flexible roles in Classic, featuring assassins, control mages and roaming champions capable of influencing the entire map. 
Kassadin, 
Ahri and 
Akali remain some of the strongest choices, combining mobility with excellent pick potential and the ability to take over games.
Akali is an exciting new addition who can quickly snowball once she gains access to her ultimate, while established picks such as 
Annie, 
Gragas and 
Pantheon continue to offer a strong early kill pressure. 
Katarina and 
Heimerdinger remain strong despite receiving nerfs, although they should be less oppressive than before.
ADC
The bottom lane meta focuses on champions who have strong all-in and kill pressure throughout all stages of the game. They tend to be somewhat dominant during the laning phase, but once they hit 2 or 3 items, they truly come online. 
Vayne is one of the ADCs that gets stronger as the game goes on, and she is a dominant late-game carry.
Since 
Graves, Lucian and 
Caitlyn were added to the game, he has been an absolute pick or ban: is it nostalgia, or is he actually that good? Just look at where we placed him! Due to the aggressive nature of the Support meta, like 
Leona and champions who are poke-heavy, such as 
Nami or 
Lulu and looking to fight early, champions with mobility, defensive tools or who can farm from far away such as 
Ashe are also good picks in League of Legends Classic.
Support
A variety of different champion types are rather strong right now. Most notably, champions with strong all-in or CC tools tend to do well, such as Leona and 
Nautilus, who both have multiple CC tools in their kit. 
Blitzcrank is another strong option with his Hook which is hard to dodge, and as most champions in the bot lane are immobile or lack mobility tools, he is a fantastic choice.
While aggression is a dominant factor in the Support role, many utility and enchanter Supports, such as 
Sona and Nami are quite good in League of Legends Classic. Nami in particular is just like the her current form, so if you love her now- you'll love her in Classic.
