Always 4k+ for each piece, meaning that with 10k you can only buy 2 pieces and MAYBE the neck/some low blue weapon. You do 4 daily quests in Tol'Barad, you can make 1520 gold per day (380 gold for each completed quest), requiring you to farm those dailies for 7 days (maths isn't my best subject at school but 10000/1520 = 6,57, since we're talking about DAYS it must be rounded up to 7). An entire week.
Also, there are players that (even on retail) were mh... let's say "leecher" players: they do not take on a profession to make gold, they only do it (when they do) for the profession enchant, then leave the prof behind untill they take a gear upgrade and must enchant again.
Let's talk now about 80k chars joining BGs: yeah, kind of annoying to play with, but let's think about it:
I play on Horde side, 'ya know, worst faction for BGs and stuff. Still I manage to win AT LEAST 5 BGs per day. The first one has a boost on the honor gained, a total of ABOUT 1.7k honor per day. Full Ruthless set (exclubding weapons) costs a total of 17800 honor. The total amount of time required to gain 17.8k honor is 10 days. Let's not forget you also gain honor when losing (40 honor points if I'm not wrong, this should speed up the gearing-through-bgs way).
To me, 10 days of farming honor (starting by green gear) to get full Ruthless is way better (and faster) than just spending 7 days just to make 10k of gold just to buy 2 (maybe 3) pieces of ****ty blue vicious, also grinding honor in BG is far less difficult (you always find enemies at Tol'Barad killing your quest objectives/killing you).
TL;DR Lower the price of this stupid BLUE SET MEANT FOR NEWBYES and nobody'll be hurt, otherwise don't complain about green chars in BGs.
