I think it was a raving success, not for what it was intended but it did have a secondary purpose.
To separate those who PvP for fun/challenge and to highlight who just wants fish in a barrel.
I think it did that very well. As those who want fun / challenge fight for CQC improvements.
The others just insult it, say it's not Elite (despite it is) and complain Elite isn't Open Only.
So CQC is a success, a huge one.
And the actual purpose it was built for, ended up being the other link in my sig, as people made their own PvP Hub.
The one I believe you moaned about because fair fights are "dull" or something.
Those who say CQC is the PvP-Combat mode for Elite:
CQC is great for some fast and fun PvP Combat. I like it. I play it from time to time. It's a good thing to play for an hour or two, just for a change of pace. It's great for explorers who want a change of pace. They just can log into CQC and have a littel combat fun.
But it is very limited. It is limited to three different ships. It has no kind of strategical element beyond "capture the flag". It does not integrate with the maingame in any way.
So my answer is: CQC is not the PvP-Combat mode of my chosing.
There comes Powerplay.
Powerplay is great for long term strategical gameplay. It is not only PvP combat but it is Power vs Power political, logistical and military competition about teritorry.
But Powerplay is centered around hauling lots of powerplay commodities and hauling more stuff. Some powers have the possibility to expand via comabt zone. Mind you only HALF the powers have this, the others are forced to do even more hauling to expand.
So where I want to go with this? As most would agree hauling is more effective outside of open, becouse you can min/max with shieldless 700t cargo Cutter without risk. NPC interdictions are not a risk, agreed?
This is why most playergroups who still are engaged with powerplay are FORCED out of open to stay competitive. Becouse in open play you have the RISK of losing a 700t cargo Cutter to opposing PvP Combat.
Of course it's fun to play the undermining game in open and this is where I have found most meaningful PvP Combat interaction with opposing powerpayers.
Also in this case, players who have earnt a lot of merits by undermining are usually trying to avoid PvP Combat to bring the merits back home. But at least you still have the CHANCE to try to follow theire wake or predict to which of theire home contorl systems theire going and wait for them there, if they are staying in open at all.
So. My point being ... PvP-Combat in open in a meaningful setting only happens when both parties have nothing to lose. As soon as there are objectives or goals involved players tend to go the most secure way and avoid combat.
That's why powerplay is not real PvP-Combat option too.
And that's why I think that ED has NO meaningful PvP-Combat content at the moment being.
What we can do to have PvP Combat is, meet up for staged wing vs. wing fights, be that in powerplay or just for fun with several playergroups, pvp-hub, ...
Or go criminal and randomly attack players be it in a pirate roleplay way or just psycho attack.
Both options are not statisfying for me. But I know, I bought the wrong game for this - despite for wings and powerplay suggesting that there would be a meaningful pvp-combat environemnt. But there is none. Neither CQC nor powerplay are.
With some minor tweaks powerplay could have been that strategical pvp feature form elite. It still can be. There just needs to be some choices to be made - so powerplay cargo and active merits can only be held in open. I know. I repeat. And it's against all modes equal. Still it'd be an easy and clean way to implement real pvp-feature for elite.
"The new bubble" is a nice Idea too, but it would locally seperate the playerbase. It's to think about what would be the worse trade off: having one game feature that has some open-only activities or having a whole fraction of the playerbase segregated to a third bubble (old, colonia, pvp)
