I agree with you on most of your points but Gally does 2 times the damage over Truth or Hunger. Burns aside Hunger is better than Truth on bosses because of the extra damage however little it may be. Truth is better than Hunger in PVP because the blast radius reaches more Gaurdians. The calculated damage against bosses show 4000+ damage for both Truth and Hunger. Gjallarhorn does 8000+ damage against bosses after wolf pack rounds. It is twice as powerful as it's nearest competitor.
