This is definitely not true. The only conditions for entering Dreadwyrm Trance are that you have three Aethertrail stacks and that the DWT skill itself is not on cooldown.

Your other point about skills "working" is correct. Bane in particular requires both at least one DoT to spread and at least one other target to spread to, otherwise it fails and you don't get an Aethertrail stack.
