I don't think Kassadin is broken. He only pokes now and his only burst is his Q on 4 stacks, which costs 400 mana. His E is a poke, his Q is a poke, his W is as it should be.
Meanwhile,
as a ranged fighter gains more on her Q, more on her W, more on her E (taunt), and more on her R.
Also,
deals more in all aspects though she is melee, she can get up close and personal easier than Kassadin with her ultimate.
who shares a similar passive, has 2 mobility spells. Yet his Q is great for closing in gaps, and his E is great for not only damage but being untargetable allows him to get away with no damage while dealing damage. His slow even lasts longer. His ultimate even deals more damage than Kassadin's after its been stacked 5 times. (Cassation's ultimate can only deal up to 360 damage for 800 mana.)
's Q deals only 10 less damage than Kassadin's but also damages 4 others. Her W deals more. Her E gives her Kassadin's passive and only deals 20 less damage than his E.
Kassadin is right now the weakest assassin. He can only poke, needs a lot of ganks, a lot of AP, and to make things even more stupid, his Q only deflects magic damage yet it only gives up to a 160 shield. It should deflect like 200 magic damage, his E needs 6 others to perform spells + 80 mana, yet he only slows for 1 second and deals a poke.
His total damage, if you are able to, at most is 850 damage. Then, his total AP is 200%.
Ahri's is 1154 and her AP is 274%.
Katarina deals 1250 damage and her AP is 360%. AND SHE'S GOT FREE SPELLS!!
I think Kassadin is that one champion people just don't like to play against due to how he use to be with his powerful abilities and OP ultimate.
They don't realize that he is so hard to use now. His Q is a poke that takes 70-90 mana yet it pokes the enemy and gives him a puny shield.
His E costs 80 yet it also pokes. Imagine having to use 6 spells to use this poke. In lane, I see the opponent use 1 ability and is able to knock out a lot of the minions, I however get to poke those minions and then wait another 6 spells to use it again.
I use my R up to 5 times just to deal, maybe 400 (this is + mana) damage for 800 mana to an opponent, unless they flash away or something.
Thank goodness my W gives back 8% of my missing mana, too bad its not even 10 or 20% half of what you get against champions. (Oh no, that'd be too OP.) Because what will Kassadin do with 200 mana? Use his only damage ability, his Q, or flash away for 50 with his R? (It's still OP, just 5 of those can gain back all his mana.) It ha a 9 second cool down. That means I'd have to wait about 37 seconds to to gain back 80% of my mana. (But, they'll compensate the damage.) Yes, dealing 140 damage in a free ability
is so OP. (But Kassadin... he's broken.) What's broken, his legs? His inability to shield himself properly? The fact he can't just get a normal cool down on his E? Or the fact he deals less damage than all other Assassin/Mages in LoL and less than any assassin in general while also having to use so much mana to use his "mobility" since he now only pokes everything?
If you find anything wrong with this.... I must admit, you really hate Kassadin because I don't see any reason why you would put
who can still lane well up there and yet Kassadin is broken.
