I totally agree with most of your points Arry.
For your 4th one, I think the idea behind overheads was initially to get all the powers closer to 0 CC, as without this extra cost everyone's starting CC levels would have been insane (but in the end it doesn't seem to have the intended effect :/). Still that's no reason for it not be displayed on the galaxy map so I wholeheartedly agree there.
Only the 3rd point is flawed, as in powerplay there often are a very limited number of good moves one can make, or at least this is the case with AD. That means those moves can easily be identified by players who understand the game mechanics thoroughly.
Following that, as far as I can tell, each power already lays out those best moves (in a reddit post on a weekly basis) according to either a leader, leading group, collective of players, etc. depending on which power we're talking about. For AD,
this is the post on reddit, and
this one can be found on AD's subforum here. As a side note,
here is the link to AD's subreddit, and you can find any other power subreddit on the right panel from there.
Furthermore, each power also uses a more secured medium where all this is discussed in length be it a teamspeak, discord, slack...
With Aisling Duval we find ourselves on the slack to decide our next move (you can read
this on the subreddit or
this on AD's frontier subforum, thank you Dinusty!), and that's where the stickied posts found on reddit and their copy on the AD frontier subforum come from.
So to sum up: frontier subforum < reddit subforum < slack as far as discussions go, and that's the same for every power (just replace slack by whatever they're using

).
Ps: Don't be afraid to join the slack, it's easy to use and the community there is very friendly. Similarly, if you're from another power I'm sure the same can be said for whatever they're using!
Thus this discussion here is less about whether or not such "orders", if you can call them that, exist since they obviously do, but what could be done to make people that don't look out for them (which is the majority of the powerplay playerbase) act according to them.
And on that point I agree with Tataboj; the mechanics in place should not constantly be pushing unaware players towards doing the wrong things, and reward less the ones that do end up doing the right one (which is actually more often then not the one advocated by said "orders", it's not rocket-science there is always a limited and identifiable number of good options).
- A perfect example of this is the fortification process: players will tend to go to the nearest systems as the current mechanic rewards this more, while the outer systems are generally the ones that are the most valuable and the more in need of fortifications.
- Another example is found during the prep process, where players will tend once again to go to the nearest ones, especially those INSIDE a power's bubble since they're the closest to any CS. However those make for the worst systems as they overlap with the ones already owned by the power. We generally want systems to be further than 30Ly apart so they don't intersect, but the mechanics make it so the closer a system is to a CS, the easier it is to prepare it.
I could go on and on and probably end up listing every single powerplay game mechanic with the same argumentation, but I assume most people that end up reading this could already do that themselves.
