1) Q/As always have an idea what's going on in the game before everybody else. The fact of the matter is while they nerfed CW well, they didn't do it how literally everybody was asking her to be nerfed. Like why make her b3 like 2 frames slower when it still does the same BS thing people just didn't like about her? Why not just change it? They have proven that they are more than capable of changing animations, adding moves, changing hit reactions etc. There is a lot more bias than you think on balance. Hell, NRS literally said they wanted to see more Firestorm players which is why they even gave him all his buffs.Well if I'm reading correctly because my head currently hurts a little...
1.) I'd probably expect that no one knew what was going on. Like look at the other characters throughout this games' life and how they fucked them. Like someone had to literally go like "Yeah, Grodd's stampede cancels are no longer plus like we wanted them to be" or "Yeah, Deadshot's nerfs make him a balanced character"
CW's actually probably an example of the opposite, they nerfed her pretty well imo.
2.) Maybe NRS is just trying to become more consistent, at least for within IJ2? Like, characters randomly getting HDK's and randomly not getting them is preetttyyy inconsistent where it probably shouldn't be. The changes made sense and there was a reason for them being done.
2) Considering how whack-a-mole MKX balance was, I don't believe it. Because the thing is, NRS learns from their past mistakes in some ways but then don't seem to in other ways. Not EVERY change has a legit (or even excusable) reason behind it; some changes just HAPPEN. It wasn't a bug, just an excuse to change something for the sake of changing it; the problem is their approach, communication and delivery.
