I mean there is a reason we have open Single Player to test/do exactly what you described before buying them. I'm yet to meet a single person who's read any weapon infocard and went based on it, the only thing people look for is numbers and those are really self explanatory. When you look at a Justice mk3 you don't read the long ass infocard, you see 8.33 refire rate, 900 m/s velocity gun, with 687 damage per second at 1,19 efficiency. What more do you need to know?
you took the easiest example.
Where are certain mechanics explained ingame such as armour penetration, sub targeting, fuze, min-arming of missiles and these are just a few examples of hidden mechanics.
Where are the functions of thrust drain explained, where are is it explained what energy damage even means? How is a new player supposed to know that not charging his shield saves them energy?
The help menu on the nav map is very much outdated.
If you want people to become decent at pvp at least explain the mechanics somewhere in the game so they can read it and understand what is going on.
Even simple new commands that were added such as docking module commands are not explained in the game or the newly added group number chat.
A lot of the frustrations that come from the community right now is because there are so many mechanics that constantly get changed and tweaked that people get confused and there is no source of the truth out there.
Saying "just go into single player" gives you a handful of answers but nothing much.
The game used to be fun because it was a basic arcade, easy to understand and you could perfect it.
New players needed help knowing what engine kill did for them, but that was about it, they got the basics from there.
Now you have to spend an hour explaining all the new mechanics that have been added, some really great, others not so great.
Without documentation and a single source of truth, people will remain grumpy because they will not understand why they lost a fight due to mechanics that feel extremely hidden.
