Perhaps you're the one that got my Registeel?
Anyway, I fit more in Category A since about 92% of the time I either:
A) Obtained it on my Sapphire/Ruby/Emerald and have since transferred them to Emerald and cloned them.
or
B) Chained the same Pokemon on Diamond/Pearl hundreds of times and have gotten many shinies because of it.
But yes, since the release of Black/White I have noticed a lowering in cost for most shinies. For example, I saw a Lv. 36 Jynx (shiny of course) being offered for any level female Mawile earlier today. It is an utter madhouse on the GTS now as a result. People getting booted and communication errors seem to be rampant, especially for Diamond and Pearl versions it seems. People seem to be
too eager to get and send off their shinies.
I digress, it has forced me to lower what I want for my shinies, at least there.
By reading this, you lost the game. Oh, and want to pet my puppy? It doesn't bite.
Sorry, no DS-compatable Wifi.
