How big is the change to MCH? It doesn't seem like it changes anything pre-50.
They're not going to do anything meaningful pre-64 at any point in the near future. For 70 MCH, it's a largish change to the flow of the job in some good ways and bad. The goal is the same (be above 50 and under 100 heat unless intentionally Overheating), and they made it take a lot longer to get to 100, and doubled the frequency of the recovery from Overheat button.
It's going to be really hard to say until getting a better idea of how it plugs together, but from a shallow perspective it got a lot easier to look cool as hell. So that's nice.
I am really glad about the Balance nerf / Spear buff. Seemed like the whole card mechanic was just "Searching for Balance Fisher" and everything else was second fiddle. Reminded me of NIN and Futon before SB and level 54.
Arrow was alright, too, so there were two cards worth using! But, yeah, marrying the Balance nerf to the Spear change is a pretty solid overall adjustment for AST. It's now 50/50 odds of drawing a card you'll actually want to use eventually, and adding in the Unspread and UnRR means Sleeve Draw just got a lot nicer. I
still think it makes no sense to not just do this in 4.0, but in practice it's just going to make playing AST better and maybe cut back AST Logs a little so... yay?
I think I'm just past the playing MMOs part of my life.
