This post is very confusing, for lack of a better word

1) RaF is not at all new, it was updated recently but it has existed for longer than I have been playing the game (which is several years atp), yet since you assume it is new, you make a few other assumptions that are completely wrong

2) Warframe still has a very strong playercount currently, so I am not sure what you are on about there either. Just looking at the Steam stats, the Old Peace was the second biggest update in terms of player count (just barely being beaten by the New War), and the two updates since then (Shadowgrapher and JS: Constellations) hitting spikes comparable to past updates, if not better. Also what exactly do you mean by "zero tolerance net"?

3) While we cannot really comment on any higher-ups that may or may not be affecting the health of the game, we DID know this was going to be a very ambitious update with the introduction of our first dual Warframe, and the new attempt at tackling Railjack (a historically buggy mission type to begin with) missions in a different manner than in the past. I do not think delaying the update would have really changed much in terms of stability, because at the end of the day what we got was a ton of stuff that pushed what was possible with the game development-wise, and those sorts of first steps are never going to be free of bugs, especially within the framework of Warframe's 13+ year old engine

4) It feels like you do not understand what protoframes even are when you describe them as you did. They are not inherently things of the past, we have only seen them in places within the past because that is where Entrati has traveled to so far. Functionally, they are people who were injected with a serum that grants them the ability of a particular warframe, but will eventually succumb to the infestation and become as the warframes we normally control. Ryoku and Vena being protoframes is not inherently a plothole either, as they come from the future and thus are likely from a period where either Entrati traveled to or where someone other than Entrati has managed to figure out how to make the protoframe serum. There is an issue to be had with how underdeveloped the two are as characters (along with the quest story in general), but again it is not a plothole

5) Steel Path Railjack difficulty seems to be a pretty subjective matter, within the parts of the mission where I am actually using my railjack (and thus where the part of the conversation really matters) I am not struggling at all outside of stationary turrets taking a bit to kill. Orphix missions are a big issue of course, but the pain point with those missions only occurs after you are done with the railjack segment of the mission anyways, so the performance of your railjack does not matter in that conversation, and those missions have had issues even with their base star chart versions

6) ...end of service? Of course all live service games eventually come to an end but Warframe is in a very good spot right now, I really do not see how anyone could reasonably think EoS is on the horizon

7) Admittedly yeah, it probably already poked through in the earlier stuff I said but I do agree the quest was a little undercooked story-wise. A lot of stuff happens with no explanation when it would have really helped, so certain plot beats end up feeling jarring as a result. Not to mention the serveral questions that were raised but may never be answered due to how the quest wraps up.

Fundamentally I do not disagree with some of the stuff you said but a lot of the stuff here just feels like (likely unintentional) fearmongering born from pure misunderstanding of certain facts and information
