if your Qing up for random battle grounds you can use Wintergrasp / Tol Barad to your advantage. ive been using this alot to get battle grounds that my faction in my battle group wins the most. If you take the tol barad / Wintergrasp Q while inside of a battle ground you get ported out without the deserter debuff.
Steps
1. Queue up for a random battle ground and wait for it to po
2. Queue for tol barad or WG ( which ever is up ) then take the Q right away
3. if the battle ground isnt what you want or your team is losing take the WG / TB Q
4. Repeat until satisfied
this is very usefull if your going for battlemaster or Justicar / Conqueror because you can skip any battle gounds that you dont need for the achievement while still getting the extra honor.
