I had to reread your comment as most of it has nothing to do with what I said and I was confused with why you were replying to me specifically, but I'll do my best to reply well anyway.
Vlad vs. Akali is a skill matchup, better player wins, even now.
That grandmaster+ comment wasn't about balancing, it was about her snowball potential. Outside of grandmaster+, where Akali is truly strong, she doesn't snowball as easily when compared to other assassins. I'm not exaggerating when I say that every assassin is easier than Akali right now, except maybe Kat, still talking about below grandmaster btw.
As I stated at the beginning of my comment, I never really wanted to get into whether she deserved to be nerfed or not, but since you brought it up: Imo they needed to bridge the incredible gap between her being so problematic in high elo, while being really bad in solo queue, not simply buff or nerf her. Which is what they are trying to do with the upcoming changes, which is great.
Again I never said anything about nerfing her passive, I'm pretty impartial to the change. I believe they nerfed her passive the deal with how she's a better skirmisher than an assassin, but they nerfed her skirmisher half without buffing her assassin half, making her just not great at either. Looking forward to these changes, hopefully they push her into being a balanceable assassin instead of an unbalanceable skirmisher.
