the sheer amount of butthurt on the official forums is pretty hilarious, especially coming from people who haven't tried it yet.
I'm sure it will get balanced further in coming patches. Specifically, I expect reloads (missile specifically) to start consuming supply such that you'll have to decide when to pull out of a fight based on what it is costing you.
Missile spam is a little silly now. There were always unlimited missiles, but they used to only reload between fights. Having them reload in fights is fine, but maybe it should take longer and cost supplies for each reload. This will probably come in the future.
I think the limited ballistic ammo in the previous version did not add anything meaningful to the game an it is better without it. Energy and ballistic weapons are still differentiated, perhaps now better than previously.
Consider though that I mainly play this game in strategic mode so I may not be the right target audience for the subtleties of the combat changes. My opinions may not consider whatever tactical nuances the arcade style players are exploiting.
I really like the random sector / dynamic economy mod, and I hope to see more of that kind of thing in this game. What I want to be able to do is logistics and trade, and wreaking economic havoc. So... this particular patch is not a big deal for me. Waiting for the next one.
