I usually opt not to whine about particulars with good games like KF, but I have one suggestion.
The hunting shotgun would be alot more enjoyable to use, or even useful at all, if its spread were not so absurdly wide. I realize that HS does loads of damage, but still it's worthless, and frustrating, if you can't ever hit anything. On more than one occasion I've double-barreled crawlers from ~4 meters without hitting them. As it is, HS is effectively a meelee-only weapon. I use it for three things: double-barreling scrakes at zero range, double-barrelling fleshpounds at zero range, and double-barreling patty at zero range.
I, and probably many other Support Players, would like it alot better if the spread were lust a bit smaller, even for just a few extra meters of range, while the damage were reduced to compensate.
The disadvantages of HS are already its price, its weight, and its suspenseful reload time. It's not nearly a viable option against pump shotty considering its useless range.
Cheers,
