Ganking/griefing/picking on newbies/etc - There could be a serious problem with cashed up pilots (I'm being nice - interchange this with whatever derogatory name you choose) are picking on new pilots in a particular system. Newbies start crying out in the forums saying, "This really sucks! I'm just getting killed all the time." Now, a number of other players could start to organise themselves and attempt to assist with the problem. Form a posse and dispense some justice to those doing the harassing. They could... or they could just reply in the forums, "Just go to Solo until you've built yourself up a bit."
LHS 3447, when the game first came out was one of the main starting areas and full of new players.
People from the Gamma testing phase were able to keep what they had earned in Gamma and some went on newbie killing sprees.
Others who had built up a small fortune in Gamma flew to LHS 3447 to defend new players and took care of the problem.
All in Open.
And you do still get the odd person from time to time go looking for new players, as we get the threads on the forums about people getting killed as new players and they have a little grumble over it.
So you do get that type of game play, not very often any more - but it still happens.
Blockade of CG - A certain group might suggest that a CG event should be blockaded because "reasons". Some players from that group will go along because they want the action or whatever. Some might say to themselves, "I like the 'reasons', but won't people just go to Solo?", and decide it's not really worth it.
FD have said they don't want player run blockades, as and when a blockade happens it will be by FD and it will be in all modes / instances.
Traders/explorers - A trader or an explorer might want to hire some muscle as a bit of protection. This (in my opinion) would be a great feature of the game but it seems the payment mechanics don't really make it all that worthwhile. That trader or explorer may take the time to come up with some great suggestions and petition FD for improvements... or they could just fly in Solo instead.
People currently do trade in open, but yes the payment is awful and even I have said I'd like to be able to top up those vouchers.
This is not a mode issue though - which is one of the things I keep saying about most of the complaints in these mega threads, that they are not solved by messing with the BGS or modes but other systems.
But there would seem to be some things (generally PvP-related) that would only really come into existence if there was a great need for them.
This game was touted as a game with PvP, not a PvP game - so PvP related game play should be a secondary concern.
And now there is a PvP arena, I'd suggest FD ignore the screams of PvPers for a while and fix those systems / balance the problem areas that I keep saying are not mode/BGS related.
Also as a side note, part of the "Offline-gate" debates, some people who wanted an offline mode said they'd be happy to have a static BGS that is never updated or has once a month updates.
FD said they only want one BGS. That they can inject stories in to and they can try to author what happens (or react to the player choices and write stories to go with what players want).
What do you think would happen, if a second server with a new BGS were introduced ?
My guess is, those who wanted offline to start with would make a little bit of noise about FDs stance of 1 BGS is the reason there is no offline.
