PLEASE report this achievement to be nerfed or removed. There's no way you can complete it if you don't have connections in Discord and win-trading. You simply can't get the achievement by playing the game as it's intended to be played.

Just got this achievement(legit) after some trial and error on exactly the best way to do it.

Firstly, it DOES take the right team to be going against, i.e. a team chain pulling flags with solo flag carriers or with minimal support. Naturally this means if there are no Supporters for the flag carrier, the other team is either;

A) Turtling.
or
B) Camping your team.

Assuming A), it helps to ask nicely for help on "D" (Returning flags), pref from a stealth class who lets the opposing team grab the flag BEFORE opening, and can then safely put him down and let you return the flag.

The Majority of your 9/9 will be from returns, but the achievement does read capture AND return, and thankfully since the opposing team was turtling i simply used my personal class abilities to make like a bandit out with it (Fellow Mages - Simply go Invisible and stand directly on the flag. Wait for distractions and then grab Flag-Blink towards the door(Near the powerup)), pop MI quickly((With the pvp glove bonus)), cast RoF on the doorway and force a FFOrb on the outer Wall to cover anyone chasing you - and VOILA - You beat the turtle.)

Its also helpful as Horde(Because Alliance LOVE their Water exit) To sit on the side perch and just freecast into them, breaking Elixirs/levitate/Water Walking and making the flag carriers flounder in front of you.

Additional tips:

For returning flags, Make sure you orient your camera horizontally, so you avoid mis-clicking the Flag carriers corpse instead of the flag.

Make friends with a rogue or feral druid to help lock down the fc so you can dispatch him quickly, and also ensure that the flag carriers actually are allowed to get the flags.

DONT BE DISCOURAGED - It takes an opponent DOGGEDLY running into your base repeatedly pulling flags for you...eventually you'll find THAT guy :P

It seems this has been fixed in 4.3. I tried waiting for the two minutes after the game was over but my counter was reseted back to zero after I got out.
