When you removed Leblanc's silence, why did you not allow her to disrupt channeling?
Losing her silence really hurt Leblanc, especially in her mid-lane match-up against Katarina. Now Sigil of Malice is just a combo-based damage nuke with no utility, something I feel is kinda... disappointing.
But when you remade Kassadin and removed his silence, you replaced the silence with a disrupt effect. Why didn't you do the same for Leblanc?
