I have never heard of killing Trolls having any effect on raids. Where are you getting your info?

Killing trolls is what enables "the ground is shaking" troll raid event, regardless of current boss progress. I've been having those events since before the first boss and still have them sometimes despite the (multiplayer) server being pre-moder at this point. It is also not the only raid event that is separate from boss progress, but I doubt our friend here has started killing off wolves or surtlings to worry about the other ones.
