When the PTR for 3.0.2 went up, it was almost impossible to test Glyphs unless you picked up the profession yourself.

Why? Because idiots were pricing Glyphs at 5000g and up. We kept asking Blizzard for Glyph vendors. We couldn't test them very well because it required either picking the profession itself up, and picking up Herbalism if you didn't already have it, and grind it from the beginning, or paying the outrageous prices. If you didn't want to get Herbalism, the prices of the mats were almost as expensive.

They eventually put a Glyph vendor in the beta (which was running concurrent with the PTR) but never on the PTR.

All so idiots could get massive amounts of gold, and buy their Epic flight training, and fly around on the PTR at Epic flying speeds.

This kind of crap happens every PTR. Something goes up for testing, and if it requires reagents, players grossly overcharge for them. So many people don't realize you don't take any of it back with you. And the rest are being stupid, or are trolling.

I think when you enter the PTR, you should be forced to read a list of what the PTR is and isn't, and the fact that no changes made will transfer back to your real character. Despite this being said on the character copy screen, it should be an in-game screen at the beginning of each character's first login.

If they are going to implement something like this, don't make us rely on the stupid players who want to profit for a character who's going to be deleted anyway. Put in a vendor giving the item away free so we can test it.
