As to why SE isnt able to change them yet, we don't know, but thankfully FFXIV isnt really that tight on reaction stuff and more about memorizing mechanics and anticipating them
So yes technically the main culprit is not the netcode but it doesn't help with other issues.
The netcode has a 100ms delay on it (as per SE back in ARR). It was brought down from 200ms back at the beginning of ARR. So if you have like 100-200ms, it's actually 200-300ms with the netcode.
Then there's the issue of actions going through via the server side of things while the animations are on the clients side. The ms issue on top of server/client not lining up makes this a really bad system for new players. It's not as noticeable for most of us who have played it forever since we conditioned ourselves to deal with it.

I'm no expert so that may not be the best way to describe it but essentially it narrows down to this.
