That's just it though, having 300 ping was not a technical limitation last patch as it was completely possible to play on a 99% fair playing field to someone who had 10 ping bar a few outlier situations. It still is mostly fair although the balance has been shifted slightly.
There is also a disconnect here when you say you aren't advocating for lagging desynced combat, you just want it to be faster.
Making the combat faster by removing the release delay or the run speed a lot faster will cause desync and lag. There are reasons it was slowed down in the first place, it wasn't just done to accommodate people with terrible reaction times, it was done to make it actually possible to react.
If you want to speed the game up enough to make a big difference in feeling and combat, that is.
As I've been saying, there are some areas that can and hopefully will be sped up such as the normal swing charge times, but some specific areas cannot be sped up dramatically without massive issues for people with even medium-high ping.
So the best course of action would be to find the things that can be sped up without compromising anything else, and collectively as a community ask to speed them up.
As far as not agreeing that high ping players should be taken into account for the game balance, that's fair enough and you're well within your right to have that opinion, but Henrik has stated several times that he wants the game to be accessible for everyone around the world, not just EU and not just NA. In order for that to be the case, compromises have to be and have been made.
