My dream patch log for LeBlanc

- W: There is now a 0.75 (1?) second cooldown before distortion can be reactivated.
Context: Giving her the Zed treatment, if she goes in with W, opponents have time to react and punish her if she did a poor engage. I would also propose to make this change only on W, and mantain the instarecast on her RW, being it an ultimate. This change will surely hit her laning, but I think it's already strong enough for an assassin.
- E: Reduced the hitbox to actually match the animation. Reduced tether range a little. Buff damage and/or snare duration.
Context: right now Ethereal chains is almost undodgeable, with his huge (invisible) hitbox and really long tether range. This change is aimed at "Separing the good players leBlancs from the bad ones" as we like to hear from Riot. The buffs on damage or root duration are here to increase the reward for a harder-to-land spell (if necessary).
- R: Mimic has now a 50 mana cost.
Context: Not much, just why in the world should it be free to cast?
After those changes, she would still be able to wreck people, but more as a Deceiver, not a lighting that kills you then disappear away. Thoughts?
