Majority of starsectorers seem to miss what's happening here. Let me be clear. It's EASY to maintain your fleet, it's EASY to earn credits and tons of supplies. But it doesn't mean that maintaining your fleet will be enjoyable. It doesn't make gameplay enjoyable. I don't think that there are many players who play only to maintain fleet.
v.0.54 gameplay was "Space Battles". But with v.0.6 gameplay shifted from "Space Battles" to "Sims in space" or "Tycoon in space".
I think that for now problem lies within game goals. 0.54 was all about battles as a game goal. 0.6 is all about logistics and thus gameplay revolves around logistics, so even combat starts to revolve around logistics. And in present state there are very limited ways to play the game of logistics. Thats why there are unsatisfied players complaining about supplies, fighters, frigates etc. The problem is not even that supplies are expensive, repairs and cr are expensive and fighters are useless in achieving game goals.
Real problem is that we have very limited range of game goals (like maintaining your fleet through hunting carriers). Limited range of game goals means limited range of tools and strategies to execute. Means limited gameplay experience. Which is not what people usually expect. Really simple and fast way to solve this problem, without touching new systems introduced in 0.6, is to give new goals. For example battle in which deploying fighters and frigates or using other strategies isn't stupid. There should be many-many ways to play starsector, just because there are CR and supplies are expensive players shouldn't be forced in few cost-effective strategies. In fact every strategy should be effective in some situation. For now we don't have that many options to choose from.
I read blog posts about new systems in 0.6 and I understand why this may be a necessary change. But these changes have to expand gameplay experience instead of limiting it. If there are only few cost-effective ways to play, you have to give new ways. While new changes may give new depth to gameplay experience, they shouldn't be annoying. Which is not a question of removing something, but tuning. Reducing your pool of viable strategies because of cost-effectiveness is annoying. Having more variants to choose from in my pool of strategies, because there are hundred of different situations and each has certain cost-effective strategy, is very enjoyable.
The funny thing which illustrates gameplay shift from combat to logistics is new pop-up with ship's info. In 0.54 it was 1 block of logistic's information and 2 blocs of combat stats. Now its the other way around.
