Why do I suck at Warframe?

I started playing Warframe in 2020 it was the second game I’d ever played(first being Horizon Zero Dawn cos it was so pretty! XD) I got into gaming while nearing my 30’s and it was because my partner and I were in a long distance relationship and this was a fun thing we could do together. My partner no longer plays Warframe preferring FPS to farming. Since then I have put in more than 2000 hours in the game and I’m at a mastery rank 25. I’ve used oh so much Forma’s. Farmed so many arcanes. Watched so many many Warframe tutorials but I’ve noticed my damage still sucks. I can barely do steel path. I still play because I absolutely love the community, the game and I have my group of gals; we chat, farm and play together but I’ve noticed in comparison to them and even many MR15+ I SUCK. My Damage is still often 3rd highest and sometime 2nd but never high. Is my gameplay just awful or is there something I’m missing! Do you guys have a YouTuber I can follow who can help me with this? Thanks a lot in advance and Lots of love! 🥰
