How come udyr can't walk though 10 cc and regenerate all his hp

Nobody sees a problem with 100 damage aoe from a guy who can tank 5 people for 10 seconds with minion farm?

Don't follow him. That's what he wants you to do. Find a ranged champion with cc and kite him from afar.

Stop chasing him then.

If you chase him for 2mins you can get 400gold.

if you want to kill singed you need a frozen mallet.

umm hey guys, singed late game runs around the battlefield, people dont chase him

Okay so a problem a lot of low elo players have with singed are that they Dont play aggressive enough in lane or even know What Champion to pick vs him . Singed is a late game champion , so you have Ho try and defeat him before that . Incase the game does go on for a long time you need to make sure you are more fed than him . Singed is just an example for late game champs who of left alone to farm will carry a game solo . You need to pick a good champ to harrass him out of lane and get your jungler to gank him early . Another possibility is to pick sth that is equally usefull lategame .
When playing in mid to high elo firstpicking singed can meab a lose since the enemy can counterpick you . If you ever have Problems with a champion always thibk about how zo deal with it where are strenghts , where weaknesses

-plays against singed
-singed kills him
-make a thread about how he is so op
-and then exaggerate how op he is while comparing him to udyr

Flawless!

Let's nerf all champs who got fed cause they need to be nerfed if they can so muuch damage if they are fed :OOO
