That's quite honestly the least of the problems. There's extremely powerful evidence that they're manually setting gold -> gem prices in order to discourage that, which I said in a couple other threads. Namely as a tl;dr:
22% increase in gem prices which occurred instantaneously with the patch (this is a greater magnitude spike than every holiday event to hit the game, and it took effect over a period of just a few minutes as the patch rolled out).
Gem price history pulled from the game UI.
What they're doing now is not forgiveable. Using new players as a scapegoat for this change is one thing. The nature of the change and the cloak-and-dagger they're pulling to cover up artificial inflation is a whole other beast, and foreshadows a really shitty future for the game.
Someone on the forums was apparently running an independent tracker on gem price over the patch period and this is what it showed:

Nothing like that has ever happened. You can tell it's artificial because (1) patch anticipation causes more up-front buying of gems to anticipate a price rise rather than a sudden spike on the exact minute of the patch and (2) there would be many smaller dips during the spike as people cash their gems in for gold before the price normalizes, rather than one giant dump after the spike. Assuming this tracker is genuine, everything about that curve is artificial.
