I actually need VoC and sword breaker as well. But I've only been raiding ... Going on my 8th week now. Hit the big five oh in completions this week. ( It's be more, but they didn't have crota raids patched into the counting right away.) While I've hit it hard, I hear others that have gone much longer and it's either the foil or vex someone is still missing. I think the vex drop is more frequent though.
