Can you accept that because of FDevs definition of combat logging that logging out via the in game menu should not be considered combat logging and therefore not punishable?
Can you accept that this is their games design and it's implementation is working exactly as frontier intend it to (in so far as the logging out menu).
I can accept why you feel it is combat logging and can understand why PvP centric people feel frustrated when commanders use the in game menu to log out. Reality is they are not breaking any rules doing so...
Using exploits such as alt F4 or dropping your cable out of your modem / router etc is defined as combat logging by FD and should be both reported and punished IMHO.
How would this disincentivise logging out during unwanted combat? You take the view it is an offence to log out via the in game option while under combat when logging out that way is not punishable and is indeed frontiers intention to allow players to log out of the game that way (at any time). Still I fail to see how it would reduce people from choosing to log out when unwanted combat starts. Perhaps if they were PvP Centric players themselves and logged out to avoid 'losing' an engagement, it would act as a punsihment but for non PvP players it would make little difference I feel.
Good suggestion, that would go some way towards kurbing random newbie killings for sure.
Yes I can understand why you would dislike those 'earning' their cash in solo then coming to open for PvP, so instead of having some risk of player piracy while trading they only have to deal with NPC's...
I do not see a solution to that particular issue because I agree with the current design of being able to mode switch at the players discretion. I do not agree with locking play modes.
CG's should be for everyone but that is my opinion on that... Indeed CG PvP is a good thing and adds a definite richness to the game IMHO, I have done a few CG's and seen some familiar PvPers in my instances from time to time, a lot of fun either avoiding them, bribing them to get through or outrunning them

It definitely adds a lot of fun and adrenaline to the game in those events.
