Balancing Le Blanc
Well, it quite obvious LB has some flaws right now and is just too strong as a 1v1 laner in almost any matchup, offering almost no counterplay to her Opponent if he didn´t pick a very specific Champion like Fizz or Sivir to stop her CC-Chain.
So my solution would be to Focus on her combo-casting, increasing her skillcap a fair bit and reducing the amount of CC and dmg she can put out the same time:
-Change the q Trigger, so the dmg (But not the silence!) proccs if it´s followed up by another q or w; if it´s followed up by the e the silence proccs (but not the dmg!).
-Similar for the chain, nerf the base-duration of the chain to 1sec, but if it´s followed by the w or another e while the chain is still attached but did not procc the root yet it should still be 1,5sec.
Right now laning against LB is very toxic, as you cannot really leave your turret unless you have clear Vision at her jungler - because it´s damn easy for her to just lock you down at lvl 3 without any counterplay (silence->root->jungler jumping at you), while the supposed counterplay to her during laning should be to push her at her own turret and Keep her there. Changing her Combo so she either does apply full dmg or set sth. up with a heavy cc chain would offer way more counterplay to her, without really denying her strenghts (high versatility, very good at catching People out) - and it would LB Players to really think about in which order they use her spells instead of just throwing everything they got at the Opponent.
