Since Cassiopeia is being looked we need a new poison indicator really badly
No other champion in this game have to interact with poison targets so much like Cassi and maybe Urgot does
I think most of us missed more than one time an E rotation to a non poisoned target in big teamfights, thinking we hit the target with poison but no and because of that our E goes on CD and we lose a ton of DPS.
Most of the times that happends because it's really hard to notice a vanilla graphic like the current poison indicator and with all the new particles and especially new skins being more improved and fancy these days they have better and more noticeable particles/graphics which many cases overlaps the poison indicator in big teamfights where everyone is stacked up
