The conflict is that I'm used to being harassed in survival games that I've grown to be defensive when surviving that I've gained reflexes & senses that I don't find anything of this sort "strange" or "alien". You can still build peacefully, yet first have to earn what you own to do so. This is Rising World with 98% animals & 2% hostile bandits that you'll still have your creative mode style quietness & calmness. Expect the unexpected though, such as the chest-raiding Racoons among others. Minecraft, Skyrim, & Silent Hunter 3 tought me that when you don't keep an eye at your back that there's a big chunk of gameplay missing from the game & that you're really not being kept in check. Not hardcore, just keeping your figurative blade sharpened. If you're not being harassed in some way then you're not really playing. Both vanilla & modding made you tough so you could survive anything, and I'm still managing to make the most of everything in the world. Minecraft may be a "kids" game, yet it went out of its way to make me learn how to keep these mobs out of the way by making chests full of stone swords (nothing less), a few iron swords, or even specially enchanted diamond swords. That, and you'd have to strafe (before the combat update) that you could dispatch these hostiles easily. That, and to just light up, wall up, and just make sure the area is unclaimable by hostile entities.
Think of it like the campfire that keeps wolves at bay, or some kind of relic that would keep monsters & such at bay. the campfire + wolves bit was constantly suggested & brought up with how to deal with hostiles. I'll however agree that Creepers, Skeletons, & zombies are "out of place" in Minecraft, yet that's Minecraft. It's supposed to be that silly to keep things gameplay challenging, if done crudely by the lazy Mojang.
I don't find it weird how there would be a 'few' (as in 1-2 every 3 hours; average session) roaming around the world. That's just an example, yet where this is basicalyl going with the frequency of these roamers, maybe even once every 3 average sessions of 3 hours. Basically 1 with a 50% chance to appear anywhere top side every 4:59 hours, or so (whatever I noted tree growth as). Again, having survived the hell in Minecraft vanilla, and more severely in 'Feed The Beast' that Rising World shall be a cake walk that there shouldn't be any push backs to this thought. More so when we're getting access to bows & arrows, crossbows, among muskets & pistols that any roaming hostile would be dispatched with ease. Even if there's herding, or not. A simple iron sword would slay them also. I've survived (with a group of friends) building up my starting place on an FTB server with zombies, skeletons, mutant zombies, & etc attacking us while we walled off the area with fences & built our home up. It became a tranquil place after that I really see no issue with. Just get yourself some iron & an iron sword then you'd be fine & home free. Having a crossbow & musket/pistol in hand would be wise, or just travel where you know its safe. Always be prepared. Then get yourself a bow & arrow or a spear. Maybe even a lance, if Red51 wants to have fun with lances.
Again, luckily we have filters & luckily Zork is trying to keep things neutral by bridging things.

While thinking of how to attack hostiles makes me wonder if we can use horse equipment while on foot. Would you find this "too alien" or weird?

Do you want to approve or disapprove of having this only on horses? In the anime world this lance & shield has become just as standard as a sword & shield that I wouldn't mind seeing it used off horses. It's up to you because change in games is often shunned that if Red51 was to listen to such that the game wouldn't update properly. Minecraft is cursed & tainted by people going "THIS UPDATE SUCKS! MIINECRAFT IS RUINED!?!!!!" after every single update.
WHat I meant to say is if you approve of it or not while trying to seek a real-world counterpart of some improvising when knocked off, or similar. I believe it wouldn't hurt to have some 'experimental' weapons of medieval weapons (realistic of course), something seen in fantasy. That fine, or nah?
I may have to do more digging if any have been used, yet I think it's only spears & shield, not lance & shield. And I do apologize for my hostilities, yet that it's now a cheapened apology because I keep having to say it a lot that it's not really going to be counted.
