I am aware of the general rule, but I was wondering whether there was any grey area here as it is not currently possible for new FS' to acquire a lightsabre.
I ask mainly because I am struggling to come up with a good IC reason my character would not have a sabre. At least, one that wouldn't conflict with the fact that he will get one as soon as construction is reintroduced.
I don't think anyone is really going to complain about you RPing having a lightsaber if you're FS. The saber construction system being down right now is an OOC issue preventing you from creating one, not an IC issue.
“I am struggling to come up with a good IC reason my character would not have a sabre”
If you're a part of a large Force order I can understand this, but if you're not I would mostly just attribute it to most of the Jedi being killed off and everyone trying to "rebuild" their forces. Would make sense that the ancient art of saber crafting might fall by the wayside to those not supremely connected.
Anyway, it's not "impossible" to "acquire" a lightsaber, as it used to be (when they weren't even items), but I agree with Meph that most probably won't care if you pretend to have one for now. Though it could get amusing when it's re-introduced, if you're currently in a RP and don't have one at that point. ;)
