Cassiopeia through the ages
Cassiopeia is a slippery lady. Always finds a new update somewhere. Through the ages cass has gone through a lot of passive changes and a few other kit changes. But what really seems to fit her? Let's take a look at what all her kits looked like.
v1 Passive: Deadly Cadence - This passive allowed cass to have a lower mana cost the more she used her abilities. In other words, the more spells she used, the less mana they cost. This passive was good for players who liked to go all in for a combo and still allow her to have enough mana to stay in the lane.
_**E: Twin Fang ** _- Deals damage when used on an enemie. 6 second cooldown I believe, and if it was used on a poisoned target, the cooldown was reduced drastically. This stayed the same until recently.
v2 Passive: Aspect of the Serpent- Whenever cass poisoned an enemy, she gains stacks. When she reaches enough stacks, she gets bonus stats. There were 3 bonuses. This passive was good for people who liked to poke, however it proved to be too powerful for the lady. Especially the heal. E:Twin Fang- Same as v1, except it would amplify poison damage, and I can't remember if this version refunded mana if it killed something.
v3 This is the current version Passive: Serpentine Grace- Cass can't buy boots but gains movement speed per level This keeps cass players on their "toes" since they can't buy boots or boot enhancements. It's good to be realistic, but it isn't very reliable and people don't even know it is there. In other words, its not really passive material. W: Miasma- Now in shape of an arc, applies new type of cc, which grounds enemies. This disables all movement abilities, including flash and grabbing thresh's lantern. E: Twin Fang- Now on very low cd, but doesn't do much damage without the power of a poison. Deals bonus damage on poisoned targets.
Summary
Lots of changes going into Cass' passive, with somewhat small changes in her other abilities. With her 2 latter passives being unreliable and too op, deadly cadence seems to offer a balance of interaction with her player. Serpentine Grace is more of a passive built in with an ability. Not saying she can buy boots now, I think that is kind of funny actually, although dunno what riot is gonna do for elise lol. Although idk why they removed deadly cadence...
Miasma brings an interesting type of play making that couldn't be used before. Before it was basically a brush checking ability. Her E is an interesting idea, however I don't think that she should recover that easily with her new one. There has to be some kind of drawback for not landing Q's or timing them right. Perhaps if it kills an enemy then it should go down as well. Idk.
