However in TES games today, weapon clipping hasn't evolved to the point where spear's disadvantage can be represented in the game, it's difficult to balance the spears, and if attempt to balance it in some way, it'll either come out as a super weapon again, or utterly useless. That's apparently not what the devs want to see.
About crossbows, I personally like crossbows because it enhances class balance (well, I know there's no defined classes, but there's still classes otherwise every character will be the same). Why? because crossbows are in fact "bows and arrows for dummies". If you are a character dedicated to sword and block, what happens when you want to do ranged attack, such as hunting? It would be too stupid to run around chasing a deer with a sword to hunt for venison, it's just not realistic. What can you do? You should be able to pick up a crossbow which is supposed to require less marksman skill (which, in real life, is true), and shoot the deer. Of course, as a penalty, you cannot reload it in a short time, so you probably cannot use it effectively in combat, or you need to switch weapon as soon as you have taken a shot. This is also true in real life combat, such as cavalry sometimes carry a one-shot crossbow, do a quick ranged attack before engaging in close range. Heck, even the ancient Roman legionaries carry a throwing spear and cast it before melee fights. So I don't think crossbow is useless.
