All of the class based weapon power DoTs required hit rolls on live (not bleeds of course).
For that matter, so did the huntress DoTs, the wyrmslayer, and the crusader one.
Unless this was changed in the very twilight of shadowbane, which I can find no patch to indicate it was. I don't know why the wiki doesn't reflect that except for the sader DoT, but it is definitely wrong. I also don't know why no one has posted about this before. I refrained from it because I thought it was such a blatant issue that everyone had to already be aware of it.
Taken from Patch 3:
The weapon powers 'Naargal's Bite' and 'Naargal's Dart' now require a hit-roll on the deferred portion.
The Huntress' high level pet has been renamed to avoid confusion
'Strength of the Stag' now has the correct effect icon
The weapon power 'Sword of Saint Malorn' now requires a hit-roll on the deferred portion.
