“[My ban with Zoe] At first I thought Kassadin was an easy matchup after s11 changes, because of how squishy he became and Katarina can rush AD early, but if Kassadin rushes seekers u will do absolutely no damage and he will oneshot you. The only way to win this matchup is by going for trades with sword either all in with conQ or short trades into all in electro before he has his seekers, after he has it this lane is doomed 1v1 and he will likely hardcore outscale u.”
“Save your windwall for his Q only if your shield is down so you can avoid the max possible damage from his poke. Don't spam your E too much for no reason since that charges up his E which you can not windwall. Get a freeze going pre 6 since he is very vulnerable to ganks before his ulti.”
“Yet another annoying match-up. He isn't much to look at pre-6, but once he gets his Riftwalk he is a NIGHTMARE. Combine that with his Q that cancels your ulti and his passive which reduces all incoming magic damage by 15% and you can forget about out-trading him. Depending on his skill though, this game could be easy early on, given that he's melee.
SEASON 11 EXTRA: He's been impacted pretty bad by the item changes as far as I've seen, obliterate him in the early game and he'll have a very hard time catching up.”
“Quite a hard matchup since he can deny your (Q + W) burst in laning phase. Land chains at level 6 and you can kill him from there onwards. Try and get your jungler to gank as many times as possible early game, since Kassadin will start to get pretty annoying to deal with once he gets his catalyst. Just make sure you can snowball off of him before he gets out of control.”
“MELEE = PUSH EARLY (LEVELS 1-2) - CARE FOR GANKS! (SPAM Q'S TILL 50-60% MANA) - Corrupting + maybe a Doran if you struggle.
If possible spam Q from a longer range and try to send him to base before 6. Post 6 there is no reason to fight him unless you have a hard CC such as Skarner because he will always escape with blinks or even kill you. Kassadin is a good counter to Taliyah because if he does not have cooldown on teleport he can easily follow you bot so try to roam only when you know his teleport is not up. Kassadin usefulness starts only at about level 11 and two items, so try to abuse early as much as you can and perhaps tell your team that too.
Beware of the teleport. Most Kassadin players will go for TP and will try to bait you into using all your skills and missing them so that you need to recall. Whenever you can try to go for all-ins because if you don't get a kill the enemy Kassadin will just gain advantage from the TP, so engage smart.”
“Once that clock hits 30 minutes, you lose. He jumps on top of you and you die. Build aggressive and encourage your team to end before 30.”
“You can poke him hard early laning-phase since he is immobile. If he runs electrocute be careful of his all in damage with ignite. Your wave-clearing is way superior so use that to your advantage to dodge him after level 6 and try to pressure the jungle and other lanes with your team. Later in the game you can try to keep him in place whenever he tries to go for your team, that'll allow your team to potentially cc or kill him. After level 6 you won't be able to do anything to him anymore.”
“The reason kassadin is a major threat is not because he will kill you in lane but because twisted fate is not the right champion to punish his scaling. Meaning a good kassadin can free scale against in this matchup. Try to punish him if you can. If he started dorans shield, you should focus on last hitting minions more than trying to poke him out of lane.”
“ Kassadin has the wave clear advantage post-6 with mana. ||
Kassadin loses slightly pre-3. ||
Kassadin loses slightly pre-6. ||
Kassadin loses slightly post-6. ||
Kassadin hard out-scales Annie. ||
Tip: Annie wins slightly early - but Kassadin is really safe - if he uses his ult correctly it's really hard to kill him post-6. Early game you win in skirmishes because of your slightly higher damage and CC. I recommend the 'Generic' build as compared to the other builds the first item power spike will help you prevent Kassadin from snowballing and scaling.”
“Its Kassadin, just avoid combat. You will be outscaled, you can't kill him because of Jump + Fleet. Your only window of opportunity is pre-6, and you don't even technically win that because of Doran Shield + Fleet.
Just don't give him any kills and rely on CC chaining in the early-mid game with your teammates to suppress him.”
