We all know the Fang of Ir Yut has a very unique ability that it is the only weapon that can mark out targets. Originally I and many of you Guardians thought this was used to track the sword bearer, it works for that too but let's think ahead. The fallen all except shanks have arc shields, the Fang has arch dmg, not only that but the fallen are the only ones that can cloak and short rang teleport at the same time. What better enemy to mark one out than one that can cloak and teleport. So not only will they be hard to spot while fighting other fallen they can teleport short or even long distance (Archon Priest). Out of sight, out of mind. The raid final boss may very well be another Archon Priest or higher with the ability to cloak and teleport if he takes too much dmg and heal with the help of survaiors. This will make the Fang essential in the next raid especially considering the boss may teleport to the background and thus making knowing where he go much more difficult. But the Fang can mark him for a short enough time for you and your fireteam of snipers to see where he goes and dmg him enough to eaither make him teleport somewhere else or return to the combat front. And knowing the fallen they will use mass cloaking and teleporting captains to their up most advantage. In conclusion the Fang is an over all great tool to use against this new raid for its tracking of possibly cloaked bosses, arch dmg for taking out captions faster, and long rang for the also possibly cloaked snipers. These are all of my thoughts, opinions, and theorys that I'm sure some of you guardians have realised and those who have not now you see the amazing aspects of this weapon. I'm very excited to read all of your comments and thoughts on my Theory! Have at it Guardians!!! Edit: thanks for the 250+ support, good thoughts. And I remembered the fallens first strike has 2 bosses so I wouldn't be suprised if their raid has 2-3 bosses.
