Issue with Singed's poison and Illaoi's Test of Spirit

Not too long ago Singed's poison was changed to deal damage every 0.25 seconds instead of each second. Illaoi's spirit duration is reduced by 1 second each time the target damages Illaoi. Simply touching the poison trail will poison you for at least 2 seconds, during which you end up losing 80% of the spirit duration because of how often the poison damage procs. This is equivalent to old Kog'Maw getting 4.0 attack speed and hitting your spirit, while running away, at the very start of the game, and makes it disappear unreasonably fast to the point that the ability cannot be used in lane to any effect. Would like to know if this is intended and anyone else's thoughts.
