The game is kinda uninteresting since 99% of the time you just follow the same linear path through 3 the tech levels. Maybe you decide if you want to get T2 air or T2 land first on some maps. You decide which tech levels you are going to be aggressive vs defensive on, and if neither player messes up too bad you go to the next one. The balance seems to be flattening the power curve so that every faction competes pretty evenly on every tech level, land units get more normalized (blazes and obsidians have been buffed, rhinos buffed, pillars nerfed, selen was made into a lab, aurora made more tank like, jesters useless, zthuee nerfed), strengths are nerfed and weaknesses buffed. It makes the game more "balanced", but also more boring. It is especially boring when there's over a year from one patch to the next. The changes brought with patches are almost never things that you change your gameplay around, the patches are instead designed to make your existing gameplay "more balanced."
At the time many of these changes seemed good, and I was in favor of many of them, but I'd rather go back to having steeper power curves and each faction having some unique overpowered stuff, even if it's sometimes frustrating it's also more fun. Could also just be that I played the game too much and look too favorably at the past. I never have to be feel fear of xerxes amassing a hidden jester snipe, and I never get to feel the risk and adrenaline rush of using a pre-OC nerf ACU to take out a dozen percies on the frontlines, or the power of your first Harb coming out prior to the T3 nerfs.
The linearity of the game is pretty much baked into the design, so is not really a balance issue, but since SACUs are not really viable at the moment they are free to be radically changed in ways that could make the game less linear. Everything I have seen regarding SACU changes indicates they will be placed linearly between T3 and T4 though.
