LAst time I checked, Driving Flight often does like significantly less DMG since it doesnt do any of the Lash damage, which is 50% if you use a chanter.
Bear pet does not seem to survive much better than any other pet in Potd.
Deepwound damage is actually very significant,
Do people not use Final Blow,? with the improved talent it kills anything sub 50% stamina if you also quality for sneakattack/deathblow.
