well, in a situation like that - there are two things that contradict each other. - on the one hand, akumabito, you are perfectly right to say that it "can" mean civil war. on the other hand - well, i get to that later...
when we assume that having an outcast ID - along with an outcast tag - and an outcast ship / equipment makes you .... an outcast. - then, by the rules, you have EVERY right to fly ANY outcast ship ( except the ones sold on guard stations owned by guard factions - however... this is a grey area, which could, if taken very seriously - be brought before igiss to decide - cause, there "should" basicly not be any player locking out equipment/ships from other players per se )
now, when you are indeed flying a ship that was purchased in a regular outcast system ( even adjacent systems might be considered direct ZoI of a guard, but they are not under direct control by the guard faction - indeed they are public to the last pixel ) and you are flying outcast colours, - being attacked by a fellow outcast could be understood as a breach of the server rules. ( or in the harshest case even harrassment )
now, we don t play on a server that is called "Discovery 24/7 rules" but we play on a server that is called "Discovery 27/7 RP" - and so, there is now the question, ... what is more important, - the roleplay - or the server rules. it is actually balanced. sometimes its the rules that must dominate a decission, sometimes its the roleplay that overwrite the rules.
what it is in that case, i wouldn t know - thats the business of those that are affected by it. but as it stands - your position is indeed backed up by the server rules, - however, the official factions position is backed up by their roleplay. - both sides are logical and plausible. - by choosing to be an outcast, even independent, you try to fit into the community of outcasts as whatever your role suggests.
if your role suggests to be a devoted outcast captain that worked his way up to command a destroyer for example, i don t think there is a problem flying one. - as that would be a solid, if not boring, but still plausible story - but of course that means, you are an outcast through and through. ( in that case - merits can be earned ingame by actually playing, but can aswell be earned by writing them down as a character history, whatever you like more )
so, i believe any outcast that roleplays as a believable outcast with a solid background - should/would not be rejected to fly the common outcast ships, not even a battleship. - now the dreadnaught is an exception as it is sold in a restricted system. - as i said before, there are hardly any rules that say that you can or cannot do about ships being sold there. - i think the outcasts are very unique there. - every other faction sells all their ships in public systems. - RP wise, such a ship could really be "awarded" - and even if i am not a supporter of players ruling over other players i believe that it can be done here ( since there is infact a ship of the same class that is public and cause i believe that the factions do handle it fair - allthough i wouldn t know - its just guesswork )
So that makes the outcast dreadnaught indeed "limited" ( and only time can tell if its an abuse of power or if its a good and healthy measure )
about the civil war thingy. - as i said before, there is room for such a thing, - as much as there is room for an outcast to fly a bretonian battleship or a zoner to fly a liberty dreadnaught or a corsair to fly a ..... outcast dreadnaught? ( allright, there are limits ) - but such a thing cannot just be "you attack me, now i can set you kos and have a go" - thats not the way to go.
the warship limitation was brought up in a RP way, and if there should be a civil war, it should be done in RP aswell. there is no reason not to have one, but it must be RPed, not just PvPed.
