Poison really isn't all that strong as people say it is, like honestly its not that big of a deal in comparison to some other things in the game, it only ever becomes a relevant thing when an ability with damage has a high level poison, such as phase fang and wretched oil, in which case you're just adding a large amount of damage on an ability with an already good amount of damage. Its gotten beaten up and sent to the pit already, but still remains as a viable option on moves such as Wretched Oil and Phase Fang, but by no means is it overpowered.
Poison is good at what it does currently, and is a worthwhile damage source available to quite a number of classes, but in high amounts it is only available to very few. If poison kiting should become a problem, well a pocketed anti toxin might help do the trick long enough to win the fight for.
