Yeah I get that but people can still kick your ass out of the fief than attack you right away...
buying gear might not be easy for newcomers.
or having rough tax too...
And it's better now when new clans can't even do that?
Besides, why would they want to not let you buy from them? The only reason I can think of is if they are at war, which means wanting to buy weapons from your enemy seems like a bad idea. Just go to someone neutral or who doesn't give an ass about it.
I'm guessing buying gear will be exactly the same for newcomers as for old timers. They haven't mentioned anything that would say otherwise. Sure, you need to get the gold but that's something everyone would have to do. They can't really give away equipment for free, now can they?
Although tax might be bad, but isn't that for the goods only?
