Can you clarify how the passive works?

As how I read and understand it, both zones are removed and all enemies that are in the two zones recieve damage equal to 8 + (1,33 x level) (+ 2% Max Health) (+ 5% AP) for each second left. The amount of seconds left is how many seconds zone 1 has left plus how many seconds zone 2 has left.

Also, Lucian's earlier E was the only ability I remember whose mana cost got reduced with levelling the skill. So I'm not sure if giving Letty's Q a reducing mana cost is such a good idea...

As for her W... If the zones get removed by her passive, the statue becomes useless. However, it is a great way to proc her passive by using W right after you hit an enemy champion with Q, since they have almost the same range.
