Yup. The severity of what you're asking to be explained is important too.
I'm happy to teach newcomers; I've explained Crystal Tower like three times over and that's not exactly mechanics-lite - but it is short bursts of content. It's not hard to take 20 seconds to explain the entirity of the Bone Dragon fight.
Trying to explain the entirity of the mechanics of Turn 4 or especially 5, given that it's several phases with distinct methods and mechanics that all have to be executed one after another, that is a nightmare.
