If you're only
doing the PVP World Quests:
- 50k Honor to Prestige each time
- PVP World Quests reward 300 Honor each (this might change in 7.1, on PTR I saw 150 - may not be set in stone)
- PVP World Quests are on a 24 hour CD (that is, 4 new ones pop up once a day).
Not entirely correct. Each day there's 3 PvP WQs with a 24 hr CD. Those are fairly easy and only require killing NPCs in a tower. There's a rotating 4th PvP WQ that has a 5 hr CD, which I believe awards slightly more honor (500? I admit I didn't keep track) but with more risk - they flag you hostile to anyone outside your party which means you can (and will) be attacked by players of either faction.
I strictly did PvP WQs, including 2 of the rotating ones (Bareback Brawl and Operation Murloc Freedom(?)) and recently hit prestige 1 on my main. Still doing the PvP WQs in anticipation of the next pet, plus I'm still rep grinding.
