I've been intrigued with the idea of trying out the spear for a while, especially with it being throwable, but my main concern with doing so has been with suddenly finding yourself unarmed after having thrown it. Of course you can always carry multiple spears, but I had to ask myself... "Is there a better way?"
Perhaps make it so that a quiver can store spears, like a bundle of javelins? Perhaps even make it so you auto-draw a new spear after throwing one? And as for potentially spam throwing(especially at short/point blank range), perhaps make it so that since you have to draw a new spear with every throw, it ties into the combat cooldown of changing equips?
