PSA ABOUT YORICK
Yorick's kit is very mysterious to most people. His passive gives him damage reduction and dage increase for ghouls being out. His q is an autoattack reset and deals bonus damage, and spawns a ghoul with 35% of his HP and ad, which loses 20% of its HP every second. His w is an aoe ground targeted skillshot that deals magic damage and spawns a ghoul that slows you if you're around it. His e is a single target magic damage attack, that heals him, Then spawns a ghoul that attacks and heals Yorick for a % of the damage dealt His ult is basically a shaco clone for anyone. It revives you if you die and it's alive. This will revive you for 10 seconds. During this time: GO ALL IN AND DO AS MUCH AS YOU CAN You have 10 seconds to do shit, so get revenge for people killing you. Running away is literally why most Yorick players have palm- shaped indents on their foreheads.
Also, you see that little green circle above the champion portraits? Those are the ults. They tell you the timers as well!
And one more thing: If you don't know what every champion does, don't play ranked. Ranked ain't time for learning about the cast of characters, it's for showing how well you can beat them.
Learning new mechanics is fine. But learning that teemo lays down explosives is not something you need to learn in ranked.
