Maridos - Broken passive Melee range

[Ravager]

I believe what she's saying is, when the opponent stands still, Maridos hits and damages the opponent properly. When the opponent kites her, due to Maridos's poor range on his attack and possibly his speed, he can't reach and keep up with the opponent to attack. Therefore, Maridos does 0 damage the whole duration if the opponent keeps moving. Samael and many other melee attack pets don't have this issue.
