Leblanc be like "Bam,you dead"

So I'm playing this aram game as malzahar and we end up getting to endgame (aside from my thoughts how aram still needs to be fixed) I did well enough and got an S(20/8/30) and all but we lost,pretty much because of leblancs champ design. In about 3 major fights at the end my team lost every single one of them because leblancs kit simply doesnt allow for enough counterplay as she jumps in and takes out the ap carry myself or the adc quinn (who ended 21/18/something) and I only have the time to get maybe one spell on her forget my q thats not gonna hit in time. I've played against leblanc in lane and its usually about the same story though it's not as bad there, how can you justify her having effectively no cast time on her recall(the q spell) for a spell that does a shit ton of aoe damage when she jumps in allows her to get in range for the rest of her kit immediately and then just poof out. How? I'm just bewildered someone thought this is good design.[zombie-brand-mindblown]

After the rework I haven't noticed this as much though I haven't played too many games and leblanc hasn't been that common lately(for me)
