Isn't it a bug that an option of Elise's spider E skill that amplifies her Passive doesn't work?

Technically speaking, there are 3 cases.

Case 1. She activates E skill at 'Enemy' immediately. In this case, Passive amplifying option of E skill 'does work'.

Case 2. She activates E skill at 'Ground', and then she re-activates it at 'Enemy'. In this case, Passive amplifying option of E skill 'doesn't work'.

Case 3. She activates E skill at 'Ground', and then she just rappels to ground because the time is over. In this case, Passive amplifying option of E skill 'doesn't work'.

In conclusion, E skill's amplifying option works only if she activates E skill at 'Enemy' 'Immediately'.

I think it's a bug, but if it's not, just correct E skill's explanation.

I hope you guys fix this ASAP.
