I really can't wait until availability becomes a major part of the game, for some reason.
At the minute, if the ship or weapon spawns as part of one of the groups, you effectively have an unlimited supply of that thing. Also works conversely, in that e.g. there will only ever be one Hyperion in Corvus.
When we have multiple systems, with a much reduced availability per system but the chance of seeing all sorts of things elsewhere? I just think it will really kick things off in terms of the game balance and the exploration aspect. For the day when we are all fielding a load of Buffalo MkII's, because that's all we can find, and we daren't bring that Tempest / Medusa out of storage because we don't know if / when we will get another one.
I just think it will be really cool.
