DismalCraft

This modpack is like spain without the s. pain. quite literally, but im just going to list a few reasons why

Creepers can blow you up with ease, hostile mobs have a chance of being extremely dangerous and can spawn tnt, you can get one-shot by a skeleton due to locational damage, normal creatures are still much more powerful than the player (usually), you have to worry about thirst and exposure, mobs can sense sound and smell, and quite a few other reasons.

but honestly this modpack feels amazing, sounds amazing, looks amazing, and smells and tastes amazing (ok maybe the smell and taste part is an exaggeration) and there's honestly no reason to not play it. There's quite a few more ores and the modpack shouldn't be laggy (it runs on most new low end computers or middle-ish low end computers, as long as ~3gb is allocated to minecraft), theres quite a few magic features as well as many more weapons, quite a few more creatures, amazing (though dangerous caves), and many more features that make this modpack COMPETELY worth playing.
