The Diligence is a DMR (or SPR), it excels at accurate fire without losing too much in terms of ammo capacity and sustained rate of fire. Use it against bots, it is a surprisingly good chaff weapon and can take good care of devastators if you aim is true. Could you just use a Tenderiser instead? Yeah, probably.
The CS is something I never bothered with - I suppose it is a bit better suited for Devastators and maybe shooting the joints on a scout strider?
The Erupton is ... special. Why you classify it as a sniper rifle is beyond me, but you do you. I also wonder what you were expecting from a sniper rifle when shooting bugs - enemies that will quite easily overwhelm you with a combination of sheer numbers and armoured support (can't kill hunters if you need to dodge a Charger). The AMR will take good care of the medium weights, such as Brood/Alpha Commanders and Hive Guards and can still take on Hulks and Chargers in a pinch. No clue why you think that a rifle-calibre or intermediate cartridge should take out armoured units.
Tl,DR: Hard disagree on your take.
I once read a fairly interesting take on this: Historical settings are often chosen to wrap the story in a certain context in order to allow the reader to picture the style and theme without having to establish and explain a new setting first, so basically you skip on world building. If you read an analogy to Zeus you will immediately have an image in mind as well as a bunch of characteristics, no need to establish that beforehand.
Now, considering this it makes sense to choose a setting people already know - the 16th centruy Ottoman Empire is certainly interesting, but the average reader might know next to nothing about it and you have to explain everything first.
Why are these three settings used so much? Well, it's positive feedback! Literature, Theatres and Video Games will select something well known and it receives popularity. In addition, a piece of media using a less-popular setting will have to a) compete with other media to become popular and b) provide plenty of worldbuilding in order to have the setting make sense. A piece of media that both establishes a "new" setting AND is very popular is going to be rare, making the entry of a new mythology/historical setting into mainstream difficult.
I'm kinda hoping they make a warbond that has an upgraded version shooting toxin laced bullets (kinda like the old Paragon), or explosive ones. And while they're at it, bring back the Double Freedom, a one-handed, double barrel sawed-off firing incendiary rounds.
Hm, ich kenne das Lied vor allem als "vorsicht, hier passiert etwas sehr deutsches" im Netz. Wenn der stereotypische Deutsche um die Ecke kommt oder auf ein Klischee angespielt wird.
Blowing into an enclosed space is chaotic, the fan has to push against air currents being deflected. Blowing into an open space (aka sucking out of you dishwasher) is much more orderly, the fan can simply pull the air out and there are much fewer air currents running orthogonal.
This is as far as my very basic knowledge goes here. You can try this effect by exhaling and inhaling air through a barely open mouth or a straw.
Ah, I was wondering where all the Karens went.
Keine Ahnung, wer diese Aussage für kontrovers hält.
At my job we recently had an old device that was used to produce the sound a phone makes when the line is busy, open, etc. . It's about arm length and 20 cm thick, you can distinguish the cogs producing the phase from the signal.
