I am incredibly hyped for the new void systems. I've been farming my butt off to get some keys for projections, so I hope it all works out.
As for abilities, yea I hate when people play Ash and just spam 4. Especially on places on Draco, it's annoying (as if Draco itself isn't annoying). But they are indeed reworking it. I bet a lot of people will be mad, but it's necessary to keeping frames interesting and not just "Press (Button) to win".
My biggest thing though, is that I hope the new map helps new players figure out what to do better. Because during my first bit in the game, I had no idea what I was doing. I had to have everything explained to me, and even then I only loosely understood. Sure, I understand now, but you have to think about new players because they are a force that keeps the game alive and increases the popularity. So yeah, here's hoping the new player experience gets tweaked.
