With the addition of different kinds of orbs of alchemy in crafting equipment, the game has become even more challenging. Of course, these items are rare to find, but a bit too rare. But this is a problem because it's really hard to find one, and even there's an increased chance of finding one in treasure boxes (which is probably the only place to find orbs, aside from missions) they're still too rare, and the best way of getting one is from the auction house, in which is excruciating to buy because of their cost. I suggest that the drop rate should be increased to lessen difficulties in finding one, but they are still quite rare.
Optional Suggestion: Bosses like Snarbolax should have a chance to drop different kinds of orbs of alchemy, but only a few will be dropped.
The drop rate right now is more than fine. The price on the AH is similar to if you had bought the orbs using energy.
At absolute most, make orbs drop outside of their specific "tier".
