Wukong is God Tier in Classic LoL
Wukong Mid is currently S+ in Classic LoL, he is nearly unrivaled with scaling and team fighting.
Why is it good?
Mid lane is currently mostly AP champions as Zed/Talon/Yasuo don't exist, this means most mid laners don't take armor runes, lethality is flat armor penetration and allows for near true damage.
How to build?
My build isn't refined but I find it is consistent and works for me.
Longsword + 2xHP Pots > Pickaxe | 2xRejuv beads | Boots + 2xHP pots > Tiamat + boots > Brutalizer | Sword of the Occult | Mobi boots > Ravenous Hydra > Black Cleaver > Maw of Malmortis | Guardian Angel | Randuin's Omen
How to Play?
Wukong is a massive lane bully, take advantage of your E attack speed / cooldown / mobility, as soon as there are 2 caster minions you jump onto the enemy champion and auto them until they run away, once you get level 2 you get Q and do the E>AA>Q>AA, nearly every mid lane will die to this when you stack on ignite and can use flash as an AA reset.
Once you get tiamat, hard push and make them burn mana to farm, when the lane bounces attack them and make them choose between minions or you. Keep your health up with knowledge of the jungler/support ganks.
Once you get level 6 with ignite, its 100% a kill.
Once you get Tiamat, start to take both wraith camps.
Get Mobi's SOTO and roam hard, a few kills snowballs you into a god.
Mid game is about roaming to stack your SOTO, go and blow up anyone who is feeding or squishy, be greedy and take everything without tilting your team too much
Team fighting is about being sneaky, hide in the shadows and as soon as the enemy ADC/APC shows up - W>E>AA>Q>AA>R>Ignite
Never go into dragon/baron pit unless the whole enemy team is dead, always look for a flank or be in position to flank, you're an assassin with AOE cleave.
What to avoid?
MINIONS! Jumping onto the enemy inside too many minions early will fuck you up, make sure you have your W to avoid aggro in large clumps.
What the enemy champions movements, Wukong is very readable so they can bait out the engage, before you go too deep make sure you know where the jungler/support is.
SOTO stacks are to be kept, don't kill yourself for nothing, play smart.
