warwick is a broken champ, combined with barrier and ignite, u can win ur lane easily, all u gotta do is pray ur team doesn't feed.
play aggressively, farm as much as possible early (use Q on cannons if u have to).
as a broken champ u can 1v1 90% of the game under 6th level, ur powerspikes are: -Level 3
-Boots + scepter
-Fisrt Mythic + botrk
ur job is to farm, 1v1 ur laner, kill gromp once in a while to refill urself, gank mid and help ur jg kill herald, fight for crab, invade.
if ur jg refuses to kill herald, just solo him.
SOME INTERESTING MECHANICS:
-u can do a lot with ur Q;
-follow flash, teleport, dash, blink, etc.
-"dodge" lillia's R, dodge zoe' sleep, etc.
-Q has delayed damage and heal, so dont be suprised if u died but ur Q is on cooldown ("WHY DIDN'T I HEAL?!?!?!?!").
-ur R is stupid, no matter where u aim ur ult, if an enemy is right behind u, that counts as "inside your ult "hitbox"", so u will ult the guy behind u, thats important in teamfights.
u can fear while ur in Q, so u can hold Q, and while flying towards crab, fear it so it loses its shield, and do damage on exit with Q.
-W can glich, you can sudenly lose your speed at any momnet, even tho ur enemy is low. this is important when u want to ult, activate W just in case.


for the champs i didnt mention, go grasp, thats ur safe rune, while dinive is ur standard build, u should go sunfire if u want to go tank.
im not good at this game, this is just my experience from 400k points. u may not like some part of it. Sveti Petar eune, thats my acc, u might see some embarrassing games :D, but go to op.gg of league of graphs, and select ranked history, a bit less embarrassing.

do i encourage to play ww? -no, learn other champs, dog wont give u a clue about this game.
