If you think that mob hp and spawnrate/horde size do not matter, you have not understood a thing.
Why use a bolter on low difficulty, if a different gun with lower damage but more ammo, bigger magazine, faster reload, better ready speed and better stability can also oneshot pretty much all the enemies at that difficulty?
On low difficulty, the bolter is outperformed by probably most other guns, simply because of how slow and clunky it is.
If your enemies only have 50 hp, it does not matter if you do 100 or 500 damage. They will die in one shot either way. But dealing higher damage per shot usually comes with drawbacks (as i listed above) that the weapon with lower damage will not have.
Why use a flamethrower with limited range, but infinite enemy cleave and good elite damage on a low difficulty, where a “horde” comes in the size of maybe 5 enemies at a time, and where elites are a rarity?
On low difficulty, the flamethrower is outperformed by most other guns, simply because other weapons have more range than the flamethrower and the enemies die before they get into your range.
Yes it is pretty basic mathematical and logical understanding, which you are clearly lacking.
Your video has one comment on youtube. That comment disagrees with your opinion on the knife.
Anyway, just because not many people have told you about them disagreeing with you, that does not mean that everyone else agrees with you, or that you are right in what you say.
You ask this why?
Hoping that my answer will be a smaller number than yours, so that you can then try to argue from authority instead of simply bringing up actual valid points (which you still have not done to this point btw)?
Either way. I am going to end our “discussion” here, since you have not brought up a single reasonable argument (or rebuttal to mine) in your 5 replies to me so far (you did not change your opinion either).
Not only that, but you repeatedly claimed that enemy hp, enemy type and horde density have no relevance to how useful a weapon is, which is one of the most obviously wrong statements i have ever read.
So… have a good day and please learn to admit to being wrong. There is no shame in it.
