Wilds expansion will fix optimization, introduce fun monsters (no shit like gore magala that takes up the entire screen and ""difficulty"" is being oneshot while hitting the health equivalent of a rock), nerf the op weapons and buff the bad ones, it's area will be an advanced white/wyverian ethnostate that refused to let in the savages from the forbidden lands (they also use cutlery for their food scene), spit in the face of gatcha while still delivering a good reason to grind endgame.
Also Malzeno makes a comeback. Fuck it, Fatalis too why not. A turf war between zoh shia and fatalis, where fatalis loses? Yes please!
Non spread bowguns get buffed (power barrel makes a comeback), focus modes becomes a "use, do less damage, but hit more" kind of thing, aerial glaive becomes viable, gunlance gets the farter rocket starter move back.
Clashes change from mindless button mashing to some kind of a quicktime minigame event that relies on monster knowledge and punishes you if you fail (but honestly that's just a bit out there I admit...).
Maps get reworked so that you're not fighting in either the equivalent of the nutty putty cave or on shitty bumpy terrain.
Also, they change the weather seasons visuals. It's an interesting gimmick but all it results in is in me climbing back to my cat-constructed sex dungeon to doze off as the monster stays in place while days pass. I wouldn't need to do this if I could see more than the tip of my nose in anything but plenty.

Like any of that is ever going to happen...
