In 9 out of 10 of those situations people claiming this or that RL is better in some way than Gjallarhorn its because the don't have it yet and get angry at the Gjally love. ALso the thrall maze - thrallway use he listed as clearing thralls and offering a few seconds of protection....umm yeah EVERY CLASS HAS AN AOE grenade, it does the same thing offers up a few seconds of relief from thralls and is suited great for dropping near the lamps while your team drops weight and clears tagging thrall mobs. NO reason to waste a RL heavy here when every class literally has multiple options for AOE protection around your teammates.
