For the pve aspect they just need a couple tweaks.
For example if you miss with a javelin and pick it up, it returns to the hotbar, but if you kill and loot it from the body, it goes to your inventory. The second wouldn’t be a problem if the one you throw is the one you use and lost most of the durability already. If the javelin is lower than 25% durability, let it break, so i won’t even bother picking it up.
I made a full session with javelins, they do have a good role in pve now, but in pvp i can’t say.
I trust @SirDaveWolf, he knows what he says!
