Greetings! I mostly play top in ranked 5's, so I thought we could share tips, strategies, matchup info for top laners. I mostly play Riven, Jax, and Darius since Shen and Malph get banned a lot at ~1300 ELO.
Try to favor MR. Akali's aren't common since bruisers can withstand and punish her burst, but I've seen them. If she farms with Q, enjoy free farm and harass. If she harasses with Q, use bushes and any sustain or soak your cham.p has. Try not to engage her in melee pre 6 if you have her mark on. Post 6, you're going to have to deal with it. Counters: Lee Sin, anyone with aoe/skillshots.
His sustain is insane. Use care when harassing as he can zone you into Rupture/Feral for decent damage. A good Cho won't get pushed out of lane easily, but it is difficult for him to harass you. Play smart, defensively, and avoid his skillshots. Post 6, he becomes a nightmare, so try and get ganks beforehand.
Believe it or not, he isn't as OP as people think. No natural sustain means he's banking on hp regen. If you harass, stay in haft range of Whirling. His pull is telegraphed, so juke or dash to bait it out. If you can punish him into Whirling to push his lane, he'll be set up for easy ganks since he has baseline escapes. Post 6, he can dive by simply building armor and health, so play more defensively. If he builds offensively, however, take advantage of his relative squishiness. Bad Darius' ks their carries, and late game can be kited easily, so don't worry too much.
Vs. Dr. Mundo:
His sustain is mostly through regen as well. Dodge Cleavers, and punish Burning Agony. Deny him CS and he won't be able to rush Warmog's, super weakening him mid and late game. Post 6, kills can only be secured with Ignite and an execute, so focus on cs control. Mundo might take to roaming if he isn't getting kills or cs, so warn your jungle and mid.
Autoattack frames can be cancelled by movement or S. Juke Riposte using this and you'll spare yourself free damage. Avoid using telegraphed on hit abilities, such as Parrley, and be mindful that her dash hits really hard baseline. Pushing her out is a bit harder due to Duelist, but it's worth the effort. Post 6, she becomes like Darius in that she can dive very well with Blade Waltz. Bear in mind it applies on hit, so Counterstrike will negate the majority of the dmg and set her up to be stunned under your turret. Punish her harass and you should be ok.
Spacing will be your biggest concern. Know your ability ranges so you can disrupt him when Decisive Strike is up and move away. Try to apply light harass to minimize his regen, and do your best to not get hit with Judgment. Most I've seen push their lanes, but Garen has an excellent escape in Decisive Strike and Courage. Even failed ganks can score you breathing room, so ask your jungler to be persistent. Post 6, avoid prolonged engagements as his execute, Damacian Justice, will score him a kill. Hit and run tactics are best.
The queen of sustain will be difficult to push out of lane. When her blades sparkle with Hi-Ten Style, dash into bushes to dodge the Bladesurge. Equilibrium Strike will making diving and harassing not worth it, so play defensively and farm. Her escape isn't great, so call for a gank to get you breathing room and deny her cs.
Push him out in early game, especially if you don't have a reliable Cataclysm escape. He's squishy early game, just don't underestimate Martial Cadence and Demacian Standard's displacement. Riven has a free lane in this matchup. Post 6, play cautiously and try not to extend past halfway between your turret and riverbush, especially sans a ward. Make him burn Cata on escaping ganks if possible.
A safe top laner. Note the cooldown on Lightning Rush and try to make him burn it pre-gank. He'll get free harass, so try to punish him for it. He's only tanky after building items, so abuse minions when he goes for an autoattack generated Mark of the Storm. Post 6, he gets extremely dangerous, so build MR to survive.
In my opinion, a toptier laner. You can't do anything about his Seismic Shard, and it makes it difficult to trade. He also scales well with armor and health, making it nigh impossible to score a kill. Farm as well as you can, note Seismic's cd, and gank for when it's down pre 6. Post 6, he has surprising burst and can dive well. Olaf has an advantage this matchup with Berserker, Vicious Strikes, and Reckless Swing, so punish Seismic and be more aggressive. Maintain pressure to keep his shield down.
Only played against once and got wrecked. She has great sustain and becomes dangerous post 6. Her mobility makes it difficult to score a kill against her, and her auto harasses well enough without spear pokes. If she pushes, call for a gank to get breathing room, otherwise make use of any sustain you have.
Nasus requires farm and is fairly squishy early game. He also needs to be in melee range to farm Siphoning Strike, so punish punish punish. Don't push your lane, though. He can farm well under a turret. Zone him from CS and experience and he will contribute absolutely nothing come teamfights. Post 6, he'a difficult to dive and may actually be more aggressive. Take his health gain into account.
More to come later...posting from my phone at work. I'd like to hear ideas and strats on how you deal with these and other champs.
