No it helps people sharpen their skills, get new Gilmore cards and points, easier ways to level up and get etheric light, some people are lucky enough to get gallahorns from the chest. After awhile ranking to rank 3 you get judgement grants and judgement tributes that give u upgraded materials, strange coins, syncs, and some times weapons. Also after awhile doing Poe u can get elder cipher from level 34. So u don't need to beat 35 to get elder cipher. I got my lord of wolves from beating 34 multiple times. These reasons are why Poe isn't a waste. My opinion it helps u to be prepared for ttk and like myself who don't own gelly. I learned how to develop strategies without use of gelly on my whole team. It made me a better player because of it. I mention this because time and time again people said u need gelly for every single thing on destiny including Poe. Learning to develop strategies for every boss like how I did makes me feel proud I prove them wrong in every way
