Latias and Latios were barely raided in our groups. We had a long stretch of both of them, and most of our area only raided them heavily the first part, and then got bored and wanted a new Legendary. This was around the Regi's as well, which most didn't really care for.
Hopefully people will be out and raiding for the shiny Latias, as I'd like to get a good IV in there. Shiny or not, not too fussed, but want to go for the IV.
As to Clamperl, I actually know next to nothing about it, so not too fussed. The Feebas was interesting because I know (from Gen4 Platinum,) how rare and how hard it was to get a Feebas. In that generation, Feebas was only available in four tiles, through fishing, of a massive lake. And Milotic is somewhat relevant and useful. Clamperl? I have only heard of it. I'll grab one or two, but really not that fussed.
