I would buy everything on my wishlist (Heroes Eclipse, Onyx Bolster Sword, Silent Night, Infernal Spirit, Steel-plated Ninja Band, Dark Cape, Lunar Cloak, Lunar Cowl, and so on). Then I would give any remaining gold to some of my friends (you have to share the love).
Oooooh! You know Lucky the Cat? Yeah, not going to be able to afford that, so no spending it on that item crying
I think I would buy a couple of current rig bundles and just TEAR through them! I love playing the RIGs, but always seem to lose, this way, if I lose, well, not TOO much of a loss, and maybe I'll win something I want, right? RIGHT?
