I could have agreed with you but there is something that bother me.
If it was a groupe a players wanting to make a pirate organisation and there only motive would actualy be in the persistente univers i would have just said " well played guys " and i would just deal with it until the problème got solved by others players or CIG.
But they do it to create a pressure point to force there message and that for me is terrorisme. There was a line between playing fair using whatever système is on and using an unfinished système to force there opinions on others.
They clearly crossed the line.
Quoting the joker : "it s about sending a message"
But I'm inclined to disagree, to a point.
Notice: In case of TLDR; skip to last paragraph.
So, I understand this sentiment, and had I not watched the stream I would agree. While I was playing the game,one of them made an announcement in chat that CryAstro was under their supervision, and there was a fee of 1000 aUEC. They were saying it's piracy, it's not there are no real piracy mechanics in the game yet. Then they said mafia. No that's not mafia either. But it is PVP, and I'm pretty sure that what they were doing at CryAstro was within the bounds of what CIG intends for this game.
If they were causing a choke point, preventing players from playing, then sure, that would be griefing. But it is not a choke point. You can get to Cellin many ways in SC, for example. They announce their presence in chat, and all of the ships that came into view during the almost hour I watched, were single seat fighters coming from Port Olisar. That would indicate that players were going there voluntarily, either to challenge them or to "rescue" CryAstro.
What does bother me about this game play is, they are well coordinated and clearly very good at PVP aspects of the game. Casually good at space combat, even with the ESP targeting bugs. By casual I mean, not excitable, can target and shoot effectively, and they know how to prioritize targets and attack quickly. I'm personally not bad at combat, but not that kind of good. Not even close.
I did have a bit of a laugh. Obviously none of them had ever done much mining. A few, including the streamer, went to Daymar to find some miners in prospectors. They believed that if they went to Shubin they'd find a lot. They did look around, but they used very rudimentary seach tactics. They need to work on this a little. But they will probably figure it out.
So. Their weakness: There is no strategy here. The only issue is they are bored, and very good at PVP aspects of the game.
They prey on individual ships who come within range. That pilot would have only seconds to react, and note that you cannot react after exiting QT for a number of seconds.
Suggested defensive tactic: One thing I have learned from PVP is, when defending against a group of co-ordinated opponents who clearly know how to work as a team, you can rely on either of two tactics: Co-ordination and team-work, or blind luck. Blind luck is not such a good method.
It would be possible to overwhelm them with a coordinated group defence, of fast fighters, and support ships that can fire weapons in multiple directions. That would be ships that have manned turrets. Send in the fighter group first, as a group, then the support ships follow a few seconds later. If your support ships arrive too early, they will QT right into the fray. They will jump an Eclipse in a second. A Warlock would be better to bring along, but the warlock might not get it's EMP off, depending how fast the pilot is at reacting. Retaliator would be a better ship for support. That's a ship that can fire in any direction in a sphere around the ship from 5 turrets, and has 5 S9 missiles to boot. If a Retaliator could survive long enough, it could begin to draw them in, and potentially thin out their numbers.
My suggestion: Jump into Discord, and practice this kind of team tactic in the PU or Arena Commander. Blue on blue for practice is fine, but for heaven's sake, follow the instructions of your group lead. Don't let your ego take over, or get bruised if you get blown up. Practice makes perfect.
