Oh yeah, 5 Ws8 St7 attacks sure is very low damage output.To elaborate hes durable and very very fast. Good for hunting war machines and other lone models, probably min sized cav too. However his damage output is very low as non-wrath, the mounts damage is non existent and so even archers will block his way for multiple rounds. Then theres the war machine thing.
Compare that to a wrath lord on crusher with 8 attacks hitting on 2s or 3s. 5 str 7. 3 str 5. 1 stomp at str 5. The damage is significantly higher.
