well i tend to find this subject to be useless as jinx said earlier most people start off big and work themselves down, its usually the mind set of a new player. you see this big shiny battleship and your like cooooooooool i want one.
im pretty sure most people will get rid of them big ships at some point but unfotunentely that is not case for some people who do just wanna fly a big ship and 'Pwnz0r' people.
also about them being the Bounty Hunters Guild in RP and RL bounty hunters may be in a guild but they usually only hunt in small packs. 4-5 men tops in fighters/gb's. now i personally dont care about them packing together to kill they're enemy, but the fact of the matter is. its still damn unsportmanlike to go slap someone with a BC and in most cases a BHGBS. usually im traveling with a group of bombers if we going near bounty hunter territory so they usually dont bother me or any of us to much, but unfortunentely not everyone is in a faction and is being gang banged by lotsa cap ships.
as for implementing rules against it, id say that is a lost cause people its already been asked to limit them in some kind of way, even i suggested it 2 months ago. it was a good descussion and flame free one also. but it is just to hard to enforce such a rule.
EDIT: i missed out a point in my 3rd point, put it this way BHG hunt people for money. now that in my opinion says they want to hunt by themselves to get as much money as possible, so unless your going against outstanding odds it would just be wrong to team up and go after a single target. less money in the end i dont think they would want that.
