Storm the Beach

I can confirm that 3.0.8 has fixed the bug preventing horde from receiving this achievement

We capped the titan relic with 6:55 left on the clock and got it.

Horde cannot currently get this achievement because it counts the time you are defending against you and Horde always defend first. Hope this clears everything up. Its not difficult to win in 4 minutes.

This achievement is easily done as Alliance, but it is one hundred percent impossible for The Horde.

As Alliance you start as the attackers, and need to capture it in less than 4 minutes, like it says, but as Horde, you have to defend for 10 minutes first, which counts, and then wait for 1 minute to start the next round, which also counts, which means as Horde, you will have to capture it in less than 1.5 min, after the Alliance have captured it in 1.5 min, this is not possible.

The only way i can imagine would come close to completing this achievement for Horde is if you cheat, you "wintrade", AND exploit a bug, you get 15 Alliance shadowstep rogues to grab seaforium, and they shadowstep up to all the cannons, so they don't have to destroy any walls before the keep, where they then place the seaforium, and afterward, Horde does the same, but i'm not even sure this will be fast enough.

You don't have to personally capture the relic to get it, i've seen The Alliance getting it lots of times, 5 players close to me getting it at the same time.

Have to say that after you have done almost all of the other achievements needed for the Battlemaster title, and you read the 3.0.8 patch notes and find nothing related to this achievement, you sorta give up.

There are also some other achievements that, while they aren't impossible for The Horde, they are a lot harder, defending the beach without loosing any walls, for instance, and not loosing any siege vehicles (all The Alliance have to do is to get lucky once and enter a battle with barely any opponents in, and win it fast, while The Horde have to defend for 10 minutes first, and surely by then, alot of players will have joined).
