There's an endless list of things they could do
Great ideas.
Number One. They must before anything, protect the physical and graphical laws within their fantasy world. All three sentinel types should not poof next to players, sometimes ontop of him, but instead on the verge of view, outside of range. This poofing business, we should just not be seeing. As it plays out now, their game, the poofing, wallpassing, infinitely armored targetable areas, appears to be amatuer hour. A talents scout's nightmare. Unbalanced, and unfair. Not the kind of code, that marriages well with surviver play.
Number Two. AI. AI. AI. The Quads need to be trained to sit and guard doorways, intimidate with physical clawing and biting. Walker needs a terrain damaging stomp. What the hell is with this orbital strike that happens when the last remnants of armor on walker is blown away. Doh, makes no sense, no frigate even up there in a bombing low orbit. Things are amiss in AI.
Number Three. That multitool shield is misplaced it belongs in pack tech slots, not multitool slots. Get rid of pistols and rifles, stick with just calling it a multitool. Sonic screwdriver, pistols and rifles, belong in other genres, not an evolved sci-fi. Phasers, Blasters, the mechwarrior arsonal, etc.. belong in NMS. Or like OP requested give ability to use their tools against them. Robot handler..
I see profit whoring code. This quicksilver vendor wreaks of microtransactions. NMS is starting to get that ever present rotten smell, that smell these other bait and switch developers produce. The ones who wanna pressure us into buying more.
You know, what really perturbs me tho.. the same Monstrosities, appear, no various types, its the same swarm over and over, it becomes obnoxious. And we cannot scan and catalog um.. dow! Something is broke. Harmless vegetable, we catalog, something gouging and tearing us to pueces, we ignore.
