I loved tinker bronze - it was impossibly easy, but also very charming and made me have strange and forbidden thoughts about suggesting having stuff creep into the main game. Personaly, I'd love it if the cutpurses stole gold when you killed them (also a nice ability for the rats if the make it into the main game somehow).
But the silver... Dear lord. I mean, it's obviously doable, and scummable. I almost had the guy but a plant spawned on top of the other altar (Earthmother seems to spawn all the time). But having the Gaan'Telet bonus items clog the shops rally makes you play tinker as if he had almost no class features and I hate shades with a passion. Plus, the Gaan'Telet junk is mostly not very good even in Gaan'Telet. Having people see all their shops polluted with megajunk is going to cause mental adjustments, I can allready see "but I thought that was a vampiric blade!" moaning, but then figuring out none of it is even convertible?
Curiously enough, the fake beard is a good purchase here
I hope it gets toned down just a little bit...
