A Champion's Tour: The War Within

With your region's Daily reset, you'll always see 2 of the 8 required PvP WQs active for the next 24 hours. Right now, it is possible to speed up the progress with alts but keep in mind that you'll probably face Level 80 enemies/players.
Here's a macro to check your progress on this achievement and [npc=223859] battle pet (tried to keep it flexible in case they reduce the number of repeats):
/run for i=1, 8 do cheevo,_,_,count,goal = GetAchievementCriteriaInfo(40088,i) if count==goal then print("\124cff00ccff",cheevo,":","\124cff1eff00","Complete") else print("\124cff00ccff",cheevo,":","\124cffff8000",count,"/",goal) end end
As usual you have to opt into Warmode to see/complete them, but it won't require actual PvP, so here are some comments/recommendations for those who want to avoid fighting players:

• 
  
• Elemental Excavation: Use your quest item to extract a buff ability from an elemental of your choice, then kill 5 Elites for 20% each, or the Non-Elites for 8/12%.
• 
  
• Along for the Ride: 10 creatures required, maybe mount one for some fun, respawn could be a problem.
• 
  
• Digging into Trouble: 10 Moles required, mount one for their [spell=439182]. (Scaling)
• 
  
• [quest=80323]: Ignore everything Non-Elite, they add almost nothing to your progress. Elite Fog Beasts leave 5-minute buffs on the ground, grab them ([spell=439569], [spell=439570], [spell=439571]). (Scaling)
• 
  
• Fending off Darkness: 10 standard Kobyss required, Arathi captives give less.
• 
  
• Bells of the Light: 10 creatures required.
• 
  
• Polarized: 20 worms required, check the 2 pylons, maybe you like their debuffs ([spell=440362]/[spell=440390]). Very close to the Mmarl Niffen camp, so keep an eye out for other players ambushing. (Scaling)
• 
  
• Serving the Queen: Focus on the big guys ([npc=220147]), use your quest ability to pull them from large distances.
• 
  

You can speed-run this achievement by doing PVP World Quests on different characters.
The way I did it is to wait for each PVP WQ, bring 5 characters level 70-80 and do the WQ on each, and you get a +1 for the achievement on each one, cutting the time you need to do this achievement by a large margin.

The only negative side to it is that, the mobs for some of these WQ are fixed at level 80, meaning that if you're not level 80 yet, you'll either have a really hard time doing it, or have to call on a friend who's already level 80 to mass clear mobs for you on each of your alt, that's of course without needing to mention that plenty of other max level players would instantly one shot on the spot.

Best of luck.

For anybody having troubles with Polarized and Serving the Queen, you MUST be in Azj-kahet to be able to see the world quests.
