I would see a reason to do it if it gave gear or something, but just killing yellows for no return seems pointless.

I ran it 6 times and helped others with their tier 1 runes. I needed a ton of blue weapons of 255+ gear score and two legendary engrams. Others used their tier 2 runes. One person received a tier 3 rune. Tier 3 requires a gear score of 300. At 256 I could not harm the hive.

It's RNG the gear can drop! Also you get higher lever rates you can you to infuse your gear up to higher levels

If your only doing Tier 1, there is little point (other than to charge up a Tier 2 Rune). However Tier 2 and 3 give out better stuff. The first time you complete a Tier 2 Court you get a Calcified Fragment...I have no idea if you get one out of Tier 3 (mainly because I've seen a drop off on the number of people doing the Court).
