Using weapons more for infected makes the needed maintenance of those weapons overly annoying. Honestly, as someone who has run 1000's of rounds through weapons w/o needing to clean them to stop them from jamming, it has always been super annoying in DayZ.
I would at least like to see firearms and suppressors not go to damaged after 3-4 mags go through them. That's so asinine that it sometimes makes me want to rage quit on its own.
If weapons lasted longer, and gun cleaning kits didn't evaporate after you use them 4 times it would be better. I really don't feel like it adds anything to the game, other than annoyance.
For the love of god, at least make it so suppressors are more robust, and pistols and pistol suppressors use less of a cleaning kit than using them on rifles.
I would personally not mind the weapons not needing fixed unless they were hit/damaged.
