Hiya! Gonna show you how to complete the Druids of the talon quest Into the Fire very quickly and without being annoyed, in my case I realy hate the slow walking NPCs walking towards something, so this is how you complete it much faster than you should, I don't think that this is intended aswell.
I start by using Enraged Regeneration (54%+ health in 10 sec) and then Rallying Cry (20%+ more health in 10 sec) then Sheild Wall (Reduce all damage taken by 40% in 12 sec), with this I'm sure to get through the fire!
Here's a video!
