Putting the Posion back into Cass
So i'll cut to the chase, and heres the idea.
Lower the damage on her E, but allow greater scaling on her posion amp. Im talking bout seriously dropping the damage on Twin Fangs. Secondly, whenever posion tick damage is done on an enemy champion affected by E's amp, it lowers Q and W's cd's by a bit, lets say .5, .75, or 1 sec reductions. Lastly increase the Cd on Q and W.
Now what does this spell for Cass?
Pros: Greater Cd's on Cass's Q and W would allow better retaliation time on her missing a Q, bringing back some counter play. Adding the Cd reduction on her E, would reward being able to consecutively landing Q, by lessening the time on her Q or W. This brings back the poison feel while keeping the feel of spamming E and having it be effective.
Cons: Only bad things I could see is this might raise her skill cap level, quite high, since it relies on Q's landing and resetting itself on E. No E, no Q, no action. It may make her tough at switching targets seeing how her Poison amp is limited to her initial target. Possible fix may be a Malzahar like spread, where the stacks will spread to surrounding targets, splitting to other champs. Ex. 10 stacks on a champ killed would spread 5 stacks to two enemy champs nearby.
So, to wrap it up, greater amp on E, with reduced Twin Fang damage and cd reduction for every tick of poison damage. Greater cd on Q and W would lead to better counter play and would reward landing multiple skill shots. That's my idea, and I would love to hear comments and suggestions.
