Yep what I did with my pally team was (from using the boa axe) to first make titansteel destroyers because the mats were so cheap and easy then farmed heroics on the pallys using shodokans heroic gold pharmin techniques and made the gold to buy four hilts, took me maybe3 to 4 days to make 20 k gold not really tryin. By the time you get titansteel destroyers you can also farm heroic fos and pos trash for your own hilts which I occasionally do if I get a terrible random like toc or something.

Another option which COULD be cheaper is to find a 3v3 team that's willing to boost you to 1800 for the arena weapons and the do 5s for points lol as most teams on my server willing to do this only charge 5 k gold this would be half the cost! Good luck
