And this would help economy rehab, how?
You would be allowing the same type of gold printing that illegal RMT brought along in the first place, just this time you'd say its ok because legal. All credits bought need at the very least to be put in the AH and pitted against each other, more sellers, better prices, gold increases in value, gets you more for the same sum. You take the opposite route, print gold just from talking to an NPC with credits in your hand, and you're diving right back into the hole you're trying to crawl out of.
Already in this thread, there are posts openly stating "lets be real, i just want my gold and eff you", which is in the back of most p2w minds, and doesn't help the server one bit. If they think its dead or dying, wont make it out of this, everyones free to move on to the next best thing. See you next week, month, whenever. Meanwhile, let playerbase inject legitimate gold into the server and put the proper value on a gold coin, thru trade runs, thru sports fishing, thru actually playing rather than call on all sorts of cop outs to not do anything and still generate money outta thin air.
