RoC is 100% weapon like in this rule (two profiles, two lanes for each). Some tournaments and people won't allow you to shoot/overwatch and fight with
RoC in same turn and they have right
RAW -wise. It's obviously error from
GW but as "we make models not games" company we probably won't see
FAQ
I would never play against someone, or attend a tournament, that ruled it that way. It's obviously not how the weapon is intended to be used.
