i don't really see how "then go into open" follows, there. if i'm not willing to put in the time, surely i'd avoid open?
the thing i think you're missing is that some things are likely to change and it's worth it to complain about them. you're right that the BGS/powerplay is imbalanced, and in many regards that probably could be something that fdev takes a pass at in the future. the BGS being altered by solo/private, however, is not where that change will happen. it'll simply have to be balanced around. fdev have established that the pvp community are a "loud minority" and are simply unlikely to cater to them at the expense of the quieter majority of more relaxed and casual players who don't enjoy that aspect of the game; ignoring that, they've already said that this isn't changing, which makes it even more pointless to bang off about it. that doesn't mean they'll go out of their way to screw you over; just don't expect them to go out of their way to screw anyone else over at your behest, even if you think that would be more fair.
likewise, PVP is imbalanced in many ways that i'm hopeful fdev will take another pass at. i think it's worth it to complain about things like the engineering system. again, though, something like the functionality of the blocklist is not going to change, and complaining about it is pretty pointless. there are some things you just need to accept and move on.
