I echo the sentiment that Mirage's version should be tap/hold. It's reliable, in theory encourages you to think about its use, and is simpler to implement than anything tying in other abilities or mechanics that potentially interferes with their use instead. before discussing the Helminth version I should state for full clarity I don't usually optimize for damage numbers or follow the metagame, and usually try for interesting things with my builds. I've never helminthed eclipse because I found it both unreliable and less interesting than other alternatives. As for the Helminth version, my immediate thought when I heard this was to tie it to emissive colour on a frame, as with Equinox and Chroma's abilities, but thinking about this that wouldn't necessarily stop people who wanted the buff, and would also leave me still not using it for the same reasons I currently don't. Nerfing it would obviously be a delicate balance since it could fill a useful niche if reliable, but that is probably the simplest appropriate response.

the problem with the New War is arguably not Eternalism. Eternalism is really easy to understand; it's just Warframe's take on the Multiverse. See Bioshock infinite, Into the Spiderverse, or other such stories. And all Warframe does with it is give us two versions of the Operator, from different timelines, being able to meet or influence each other through the void. It's way more straightforward than people make it sound. The problem with the New War is it effectively had to run through too much story too quickly, and didn't give us enough time to really piece it together. Ever since the Sacrifice we were repeatedly told to see Natah as an enemy. Then, with only one or two very easily missed and ambiguous hints as a warning, the quest proper jumps straight to Ballas killing the lotus, who is no longer acting like Natah, while we try to save her. We don't find out how Erra got into the picture, or how Ballas got control over him (or why he bothered pretending to be enslaved and gave us the Paracesis, except that he presumably wanted us to kill them for him, which never comes up if so.) Similarly, the threat being built up is the huge sentient armada and the mother leading them, and then the mother turns out to be dead, the armada... kind of just goes away because Ballas resorts to Narmer brainwashing instead, and the actual final battle is completely different to what we seemed to be being led up to, except that the Sentient mother's corpse is used as a doomsday weapon. One thing that appears to have been unintended on the part of DE is because Duviri came out after the New War the Drifter came completely out of nowhere instead of being a cool saving throw, but beyond that we kind of came in at the end of their story which started in Duviri, which we still don't have the middle of. All in all, it's less that it's complicated and more that it swerves a lot at the expense of build up. The Second Dream and the War Within obviously had a much shorter run up, but they both had a single clear story threat all the way through; save the Operator from the Stalker, save the Operator from the Queens. I feel like a lot of the story quests since the New War have had similar problems with not having clear stakes or it not being clear what's going on, although Whispers in the Wall is an improvement on this front, so I'm certainly not giving up hope.
