The only potential issue with Linked is that I don't believe there are any Linked personal scale weapons... but it's not necessarily broken on its own. With Linked 1 they could get one more hit in against the same target. The real problem is that Linked appears to bypass soak for the second hit, just adding damage on top of the total rather than being treated like a second attack.
That is incorrect. The damage of each hit is reduced by soak/armor.
Don't know how I read that wrong. Yes, the entry refers to additional hits and all hits are subject to soak.
