I tend to agree with what Jinx said in the first page of the threat.
Having caps "open use" is very different from area to area and role to role.For exanple,flying a snub in the house space is ok because most of th Lawfull will tend to ignore you because caps really lack the speed to intercept things so in house systems there is a fragile balance,pirates want to get in hit hard and bail fast and a cap wont do good at this role since it will draw attention from other caps while snubs will most likely draw attention to other snubs,but if you depart a bit from the general population area and head to the Edge/Borderworlds you will notice that a cap is a "must have" in therms of survival,here you will most likely encounter other "big guns" and the primary reason to this is that most people buy big ships to farm missions more effectively,thing that a bomber wont handle.
THe ships system is very balanced as is,mostly....
Liberty has(had) its daily Freelancer pirates brawl while Corsairs had their daily raids from RM/Hessians/OC.In the first example the cap is not necesarly but in the second is a must.Cap battlestake at most several minutes,depending wich ship clas vs wich ship class but snub fights take longer expecialy if thir pilots are experienced ones and while you say "CAPS EVERYWHERE" that is not ture,most experienced players chose snubs to show their skills and skills you need when flying snubs! You basicaly need no skill to fly a cap but dont think that if you will stay solid as a stone and hit things you will survive.Apreciate that new and weack players fly caps,apreciate their lack of skill and their numbers
I mainly expanded the ideea Jinx had and probably failed to explain it better,but you really must to be there and do that to really see any difference.
