Tier 1 raids spawn decrease

Since the arrival of Tornadus there hasn’t popped a single tier 1 raid egg in any gym of the zone I am, literally. We are a wide group of persons all reporting a wild decrease in their spawn to the point of absurdly low and no one seems to have seen one of this raids either. I don’t know if they have rigged it to force players doing bad tier 2 pokemon such as Magmar, tier 3 without shiny chance and a purposeless legendary, but then I remember the Sinnoh stuff they just added and see it stupid. Also they have done similar things in past such as crapping Tier 5 rewards when Terrakion was in raids and inflating them in T3, I’m sure you remember it.
