The solution is really simple and you'll even have money to do other things!
If i ever need gold ingame, what i don't see happening soon. I can easily buy it, if you want to play for free you have to accept you'll be spending a large portion of your game time grinding and not doing what you like.
Also 250K is not much, let's say you're someone who plays a lot to the point you don't do anything all day but play video games. You'll have several chars at max level easy since i work full time and i have 5 110's kitted out. Just having 2 of those and selling crafted lego's at 50K each every week will put you at 400K minus the mat expenses and you'll easily make that 250K. If you play that much and can't generate that little gold you're doing something very wrong.
