Kaye Toogie is a vendor for difficult to get engineering pet recipees - 3 different dragonlings - 2 pets and a level 50 trinket. These are limited supply options. According to the undermine journal the pet recipes are sufficiently available, but the trinket recipe is in very rare supply; with prices across servers ranging from a few hundred to 10,000g. The servers with undermine journal recipe prices at a few hundred do not have any supply.
You get to her via the Engineer Wormhole generator, but it is very rare. Apparently you can't camp her either - as she is only active for the first hour after your teleport.
Admittidly, I don't use my generator every cooldown, but tonight is the first time I have managed to get the Underground option. Woo Hoo.
She was sold out. Sob sob.
Once bitten, twice shy - I have clear evidence that Riot games rigs ranked games to give advantage to paying players. But I don't give you that evidence yet. You got to believe me....
