not an exploit. at this point i would like to stress that 5c is not the problem, but the symptom.
It is the problem, as it is players playing from the inside of your own power when it should be confrontational.
5c (spying, infiltration, sabotage and treason) is to be expected in any game based on organized conflict, just as in real life.
If it was designed to be like that, when if you scan certain points you gain intel like fort levels, traffic patterns etc to undermine then it would be valid and a proper mechanic.
"Good morning, Churchill, let me introduce our latest general, Adolf Hitler."
"Sieg Hei......hello! I am ready to serve you!"
"I don't know Attlee, he looks a bit shifty."
"Nonsense sir! He's been with us for a day and he has no CV. We can trust him implicitly. What should we do next, Adolf?"
"Bomb London!"
that's why groups need to keep sensible comms tight and police their ranks and territories, and that's actually part of the game.
Which is impossible if everyone gets a vote regardless, can swap allegiance without penalty, has infinite commanders on console to vote, and/ or can buy alts on PC.
of course if instead of a proper multiplayer environment you have everyone grinding away solo in private universes then there's little the group can do about it ... except stepping up their own grind or 5c'ing the opposition.
Which then destroys any logical semblance of adversarial conflict because it them comes down to how badly you can play on the inside rather than show skill and strategic thinking outwardly.
playing powerplay and complaining about 5c is like jumping into a fire complaining it burns.
No. Complaining about 5C is highlighting severe flaws. If it was that superfluous why is it every PP update talks about or is trying to mitigate it?
yes, open only would be a mandatory change for powerplay to be even taken seriously, and it would immediately expose a host of other flaws showing why a proper implementation of powerplay is not possible in elite.
It is possible, it just takes balls to change the bits that are flawed with it.
