Great diagram Kadi, thanks!
My only suggestion - although may not be too viable not sure - would be to group up the ranged around each of the 4 de-cursers just a bit more (rather than purely even dispersal) - so that it might be easier to distinguish if the fire is headed for your group/neighbor.
as Benea said:
might be good if groups ran away from flame trails together if possible in order to keep the trails o' fire moving in safe directions.
Also, we need every class with a reset to remember to use them if they end up in flames (iceblock, clos, etc) and i know i will be having my pvp trinket equipped incase im feared and about to run into a flame trail.
We dont want anyone to die, this is the way of love! LOVE WILL LEAD US TO VICTORY!
