Too may mechanoid raids when colony has good relations with human factions

[glob]

It seems like in the latest versions of the game the raids which won't happen because colony has good relations with a faction are replaced with mechanoid raids. I think in earlier versions there were more pirate raids instead. Can anyone confirm this? I think having so many mechanid raids is quite boring.

It depend how much colony wealth you got too.
At higher wealth more mechanoids will spawn because mechanoids have a higher value then raiders.
