I think that it makes the idea of Jumpships a bit more complicated.The fact that other house cap ships are not allowed inside a house is what makes jumpships hard to use,if not impossible.Since mostly Zoner caps are the ones that are used for jumping(I think it is a bit OORP,though I am not sure of what the people have RPed to acquire a Nephilim/Aquillon to use it as a Jumpship)
Maybe we can get to modify the restriction of foreign caps like "Other house Battleships,which are neutral can be allowed in the respective houses,but without docking permissions."But I am not aware of the exceptions to the current rule.I could not see any other problems that might arise with this.If I am wrong,please correct me.
