I see and have seen this game gaining so much traction from legacy players, a new younger audience, and just in general on all social media/youtube over the past year or two. Audiences you wouldn't expect who too play for the weird social interactions, the non recreate-able feeling from the pvp, and the environment/world of the game. I want this to continue and DayZ to do well so here are some changes, tweaks, and additions the game needs to be top tier triple A golden. These are what I've seen and best I can summarize.

-More weapon attachments & rarer military guns. (Bipods!) Most people agree a loot pool like this would make fully assembled guns much more rare, valuable, interesting, and continue the loot loop. You also get a lot more love out of melee and low tier weapon fights as well. Longer gameplay loop duration/interesting fights & gear fear.

-A few more weapons for that sense of accomplishment/endgame factor. An LMG to find at heli crashes (M249,M60,PKM, any work), heavy, recoil like the vaiga but long range and rambo fantastical.
Another military or shorty shotgun, and making that exotic sniper exotic.
SV-98 was a great choice. Just needs the scope and bipod to create a new dangerous interaction for players. People already use the Tundra to hit at 600m (myself included) it feels odd the best sniper is a farm rifle.

Also I believe adding more attachments to guns would fulfill people's gunlust as it makes them more varied and feel new.

-A new set of armor, Ratnik.

-More clothing for that character customization and sense of feeling unique and like you've survived.
Hoodies that can go up, open jackets over them(use the backpack slot idc), jackets over armor, leaf helmets, etc.

-Bulletproof(ish) humvees

-Bikes, dirtbikes, planes, and helis.

I know you're already working on medical, camping, and survival aspects. Great and thanks. These quick additions I think would really maintain interest & vary gameplay/continue it & change it for the better.
