And they did badly, they wont be seeing much game time on the second day except maybe skarner or morde.
Renekton you play safe early (except if youre Riven/Lee/Darius or anyone that does really good DPS early) But once he has rage bar you can't fight him at all if hes level 3-4 because he will win that trade no matter what. If you dont have an advantage early theres no way you can beat him at 6 cause of the extra health DPS and how much he can heal with raged Q. But Renekton is open to ganks cause he is a lane bully and tend to push the lane. Even ask your jungler to zone him so you can gain EXP and farm while he cant, mostly if his minion wave has built up so it pushed to your side instead.
He starts to fall off because he is easy to kite if hes not fed. And doesnt do damage if you have armor. If youre Irelia you can just build any armor item early (ninja tabi and sunfire/deadman) and youll beat him if you max W on her. Yorick outsustain him. Malphite builds armor naturally but loses early but Malphite is easy to gank for. Maokai just build tanky and he wont do any damage to you. Jax 2 item powerspike will beat him even if he has 3 items. Nasus starts to beat him at 250 Q stack or 300 (without dying ofc, play safe til then). Rumble can damage him without him dealing damage back. Shyvana can beat him at level 9 or whenever she gets tanky or botrk.
Riven, just care for her level 3 powerspike. If she can animation cancel, then youre in for a long day, play safe if she can. Riven is very squishy early game and very easy to read what she wants to do. If youre really squishy (more than her) as well then you shouldnt have pick that champion or you have to play safe the entire laning phase or wait for jungler. Avoid getting hit by her AA passive (with Wukongs W/ Irelia E/ Renekton W/ Jax E, things like that) because thats most of her damage early game cause she prob has to waste 1-2 Q to actually reach you. If youre under 50% hp and she has ult, dont even fight her unless you have ALOT of armor. Sunfire early or armor item early is the best way to face her. If youre ahead you can build damage and just watch out for her AA passive and if she hasnt used Q. She is also a lane bully so shes open to ganks as well. Tell your jungler where the ward is and tell him to get a sweeper if he can. She falls off because its almost impossible to get her full combo if she doesnt know how to animation cancel (which most dont know) and even then she won't do much damage without getting ahead because the front line is too tanky and the back line is too good at getting away and kiting/orbwalk/cc (saying if yorue good)
