((Starting a new gang would mean going without a magical source which would mean that your stats will suffer, you won't be able to do more than basic magic, your pool will replenish slowly, if at all, and you'll have to use either time consuming research or undertake dangerous missions to expand that knowledge. And you'd also have to hide from the other more powerful people and factions. And you won't have much luck getting NPCs to join you looking weak like that. And magic is rare. And knowledge is akin to a character stat. It takes time to gain it. You can't just read a spell off a book and cast it like that unless it's really simple.))
((Judging from the way piecewise described it, if you know magic you're good and don't need the group to stay in contact with your "source". So your point isn't that...right. Some of it's good, but that is basically saying that
small gangs will be at a disadvantage--and not even enough that they
don't exist.))
((But all of this is basically us trying to guess what's in piecewise's head.))
