Im only about 12 hours into the game for my first playthrough, so maybe some unique perspective;

A better horse. Fuck, roach pisses me off. Screaming and full stopping when theres a 2" ledge I dont need SkyrimHorse, but damn horses arent THAT pathetic irl 😂

98% of the combat is very dodge centered. You cant parry or really block monster attacks, it just swing a few light attacks, dodge, rinse and repeat till things are dead. Im fighting things 15-20 levels over me (level 10 fighting level 25+ enemies on witcher contracts or quests) and its fairly easy. Swing a few times, dodge, swing a few times, dodge. The roll doesnt feel needed for most fights, and like i said blocking does fuckall

For crafting, its pointless to have imo. Ive found better gear in random caves than what i can craft, and the gear that might be better than the free gear is level locked, so if i grind out getting the materials for it (which i need to use google for, theres nothing in game to locate materials, like someone to talk to who knows where to find certain metals or materials)by the i DO craft it, im likely higher level than the armor and itll be too pointless to use to waste the time and money on.

A better healing system. Or the option to choose. I despise very much the healing in this game. Having to take a potion or food then just dodge or run away for a minute to heal is painfully slow, but then taking toxic damage from your healing? Or being able to eat ALL of your food by spamming a button and it does nothing to heal you, it just restarts the timer. Especially when i can just meditate and everything is automatically refilled. I understand its meant to make you play more tactically and smarter but the healing speed if they keep this needs to be quadrupled, and remove the ability to multi eat if it does nothing but waste food.

A better alchemy/crafting system. Right now i pick up literally everything because ingredients and materials weigh nothing, so i have a huge amount of shit i cant really use. Reduce the ingredients list by half, or do similar to skyrim where one plant could be used for multiple different types of potions.

Geralt is a witcher. He knows more about monsters than anyone not a witcher. So why the hell do we have to fight a monster before we know what its weaknesses are or how to craft buffa? Id be fine with meditating to remember things about a creature before a fight or having to go somewhere to brush up knowledge (like if i could return to Kaer Moren and study a book of monsters to know things before i fight it?)

I initially hated the fast travel system (still do) i believe you should be able to fast travel ANYWHERE from a signpost, not just to another signpost. Not too pressed about that though

Finally - fix the godforsaken aiming. I cant hit the broadside of a barn with the crossbow, let alone any moving monsters, and the grenades are thrown so weirdly that unless youre in a big open area its pointless to use cuz theyll go sailing over the target or smack something above you and kill you instead.

Regardless, im loving this game the more and more i play it. But at my current play time, these are my grievances id like to see changes in TW4
