I was tempted to not post this, however, in fairness, I suppose that we should post the beneficial bugs, along with the bad
The dark amethyst armor crystal (I currently have 2 in my inventory - been doing the new T2 quests) has an incorrect level requirement.
It does give +25 strength, as it should, but it is a T2 gem, and thus should have the requirement Current School Level (20).
Right now, it is Current School Level (1)
Don't know about other types of dark amethyst crystals (tool, weapon, necklace) as I usually pawn low tier crystals off without noticing...and have none available to look at. It was sheer dumb luck that I noticed this bug on the armor crystals.
As it sits, it appears that newbies can socket a crystal immediately, that they shouldn't be able to use, until level 20.
