It is true that a lot of what you call “content creators” left the game, you see it as a deliberate act to make the game safer, while CCP saw it as merely cleaning up the code around certain mechanics that resulted in gotcha events which those people relied on. Psychotic Monk was finding it more and more difficult before the illegal toggle because the prey was disappearing from the game or not bothering to mentor new blood and that last part was what made CCP apply that toggle. You can get hung up on debating that, but most games are social contructs, especially those built around co-operative play.
You have an opinion that this made hisec less interesting and you are right, it has made hisec less interesting, however I found hisec less interesting because I had no clue what the mechanics would do, so I just kept well away from that content and most people were like me, it was only new players or those who were quick to anger who fell for this stuff. I remember with a laugh people telling me that if people came into your mission site just warp out because you have no idea what the mechanics will do, I found it hilarious and rather bemused that game play was based on this., even if it was funny
I am focused on the loss of a large group of players that were the content in hisec, my view is that by allowing such an imbalance in the protection of mining ships in terms of their tank against a buffed DPS from destroyers that made it too easy they cleaned out of hisec a fairly large group of players that were giving content to hunters in hisec. And this has resulted in the stale game play in hisec here and now.
Add to that the moving of new players straight to nullsec in Karma Fleet, Brave and Pandemic Horde and you have the issue for hisec.
CCP is not going to stop ganking it is an integral part of the game, nor are they going to stop war decs, they will however adjust the mechanics and game balance around them based on the ecosystem that they see. As many people in here have pointed out the mechanics are largely fine, with some adjustments needed. However what is really needed is rewarding co-operative play that benefits people who work together in an active corp and who develop the skills and attitude to stand up for themselves.
I see signs that CCP realise this, but they need to do more. Now you can come ito threads like this fire off you normal strongly felt broadside cause a few emotive bursts, embarrass yourself and then withdraw with the feeling you have shown them, but really! I agree getting those people back in the game with something they can exploit would be a good idea, but do you have any suggestions?
So what? It was still a lot easier to use destroyers…
PS I love hisec mining in the Orca
