sorry "open only" elitsts, FDev said from the very beginning that all modes are equally important in the Elite universe and that's not going to change.
I don't see why people are so rabid for "open only" to be the only place where pivotal events are decided. Thus far in Elite's entire history, every "pivotal" event was trolled and ruined in Open.
Many open-only advocates don't seem to understand that even if an event is open only, there's no guarantee they'll even be matchmaked with the players they're trying to oppose. I can fly in open all day in the bubble and never see another player, apart from at hotspots, and even there it's not a 100% guarantee. Granted, a CG-related location would be such a hotspot, but with the P2P instancing mechanics there's no guarantee any actions I take for either side could be directly opposed anyway. Which incidentally would impact what I could contribute to a PvP focused CG - it kind of means I need to be able to guarantee to be matchmaked with other players - but what if all the players in my instance are on my side? Plus I can block any player I don't wish to play with, which is as it should be (given some of the jerks I've come across from time to time).
And of course they tend to omit the private group option in their open only assertion. So if there were ever to be a PvP combat focused CG, those private groups cannot be excluded as PvP is quite possible in such private groups if the group's rules allow. And from open they can't directly oppose participants in those private groups. But hey, let them continue to flog the dead horse as much as they like....
