ilvl 700 gear from PvP (the base ilvl, not the 730 PvP ilvl) was better than Normal HFC gear, better than Tanaan BoA tokens. 10 weeks into the last season, you could farm out a full set of conquest gear in Ashran in like a day.
And that was the fastest way to get HFC Heroic ready on an alt, just farm out Conquest, skipping large swats of PvE content.
