What always inspired me in Rosemi was how she would always do her best despite being lowest subbed chuba (at least until Reimu arrived). However, looking at her content it doesn't seem to be the case anymore, let's look at her journey, milestone by milestone:

>100k
Cooking stream, attempts at Minecraft hardcore runs, Cuphead streams that were benchmark of her solo streaming for me (good mix of doing her best + taking breaks to talk to her chat and cool down, decent length of streams and clear goals, probably the best organized playthrough of the game she has done so far).
She also participated in singing relay, prepared the midsummer night stream, tons of shorts and small skits, sometimes for the stream itself (like skyrim intro). She bounced from game to game but looked promising, very charming and shy girl doing her best to hang out with buds. She even did guerilla streams and morning stream to hang out with the chat before/during work.

>150k
amazing membership celebration and birthday stream, more asmr, pumpkin carving and halloween stream, game show, rosemi night live, skits on regular basis. more collabs but still tons of solo content + creative one at that. She played a broad variety of games and the problem with her not finishing them started to be evident.
She was probably aware of that since she started playing some short retro games that took 4-5 hours to finish and cleared some of them. Very comfy times and probably the best celebration stream so far.

>200k
streams like fnaf and twd became the focal point of her solo stuff, she played some other short horrors like dreadout and poppy playtime. only few creative streams, mostly detective stream and 1 cooking stream (valentines day). she started to become reliant on handcam too (floral arrangement,mre stream). Her content was further watered down with ygo spam and lots of collabs. Some of them were organized by her but most of it was her joining stuff.
Really bad 200k celebration which was a disappointment for many people. she released only 1 skit.

>250k
ygo and collabs, that's pretty much it. the only new single player game she touched back then was silent hill 4 which is the worst game in the series. she also played sa 2 and a bit and finished some fnaf/twd games on her way to complete the series. Barely any creative streams - her april fools joke stream lasted 15 minutes and the joke was that "there is no stream LOL". Pizza cooking stream was really bad because of the lack of prep and turning it into a collab midway. 250k celebration itself was decent and definitely a highlight of that period of time. no skits, uploaded 1-2 shorts.

>300k
pretty much another uneventful period, she focused on minecraft/valorant/asmr and finishing fnaf games. did some ygo streams, including the tournament. her only "creative" streams are a tierlist and speedrunning irl, both relying on handcam and overused jokes to carry her through. no skits but she started uploading shorts picked by her clipper on her days off. lots of collabs of various quality, no playthroughs of games, she sticks to 1 time content like duolingo or unpacking etc.

I mean if you put it that way you can kinda see that the amount of effort she puts into her content dropped drastically. I remember her saying she can spend only 30% of her time and energy on streaming due to work reps. to think that 2 milestones were achieved when she dropped her job and despite of that they are objectively less eventful and have barely any highlights in terms of streams/vods/shorts is pretty sad.
She became overeliant on collabs/generic, low effort stuff to fill her schedule. Creative streams are usually just doing something with handcam on and acting like cute uwu girl. She doesn't pick up any single player games that could turn into longer series. At this point I kinda don't want to be with her on her journey to 400k or even 350k. It also highlights another issue with her - only her journey from 0 to 150 k was fun, creative and varied. If you don't like TWD/YGO/FNAF or collabs, the 150-300k period barely has anything of value for you, even if you are a long time viewer. And I think it shows even in how other nijien approach her.
next time they praise her pay attention to what kind of content they praise - it's ALWAYS stuff from her pre 150k days. after that finding anything worthwile in Rosemi's content is really hard. That also slays the rrat of people turning on her over 2 months. The issue was there for 6 months or so, it's just that people kept giving her the benefit of the doubts because of burnout/wagie days etc. Only when she dropped her job and didn't improve her content, people had enough.
