Another way to get great fashions, if you like black, is Battlegrounds. I’ve been doing the Corsair Stronghold over and over to get costumes. To get a costume, you need 7000 points, which you can get in about 3 long days of work in the Corsair Stronghold. Starting at level 30 you can queue for the battlegrounds. I’ve tried the Kumasylam, and you may like that one. The Corsair Stronghold is sort of Storm the Castle kind of event where each team of 20 toons alternatively tries to storm and defend the castle. Each run takes 10-25 minutes and gives you from 150-500 points depending on Lose or Win. And once a day you can do the Pirate Daily quest, which gives good loot and 200 points.
So as it turns out it doesn’t take that long to get your 7000 points, and along the way you’ll get a couple levels, and maybe a couple of hundred Gold in loot mailed to you for your wins.
But don’t take it very seriously, because you are going to die enough to get the Black Death achievement for dying 100 times and the “Death Eater” title.
