Hm-m, I do get some of that. Though - let’s first postulate whether we’re talking about current state of things on live, or pre-nerfs. Because, unless armor penetrations nerfs are reverted, javelin is not a weapon for hordes anymore in any shape of form; dead and gone since it doesn’t pack a fraction of its former AoE effect. So, that’s off the table if we speak about current state of things.
I do get the comparison with longbow, I really do, and I can see the potential for javelin to overshadow the longbow as an easier no-frills no-strings-attached version. Some advantages of the longbow will always stay (sorcerers probably would be the best example, they’re often at range that makes them hard to hit with javelin and two body-shots is often not an option before it teleports - here, moonbow and longbow shine because you can either score a headshot easily or do charged shot + light and let bow finish the target off after it teleported), some may be eclipsed. I’d hope the damage dropoff on javelin on far end of the range offset it.
The moonfire bow - well, it’s tricky. Yes, it’s viable as things go now (even if it loses to longbow), since it hits important breakpoints. But I’d argue that moonbow’s burst is higher than that of javelin, you can do more shots back to back. And that’s where I’d get back to my point about things fun and unfun: the drawback of cooldown is also moonbow’s fun side, because nobody ever enjoys being excluded from combat. The javelin’s manual reload is actually a huge drawback, and making it slower is something I consider a bad design because it excludes you from the game entirely. Yes, you can make an argument that others have weapons with manual venting, but only as an addition to (slower) over the time passive recharge, or manual recharge weapons like brace of pistols - but you still can fire them, just at slower rate, if you’re out. So, moonfire bow design is actually a good one, it lets you switch to melee and actually do something, reposition, get defensive, until a few seconds later you can kill that special. In case of javelin, make it slower to reload, and you’re just reducing the active combat time of a player and making them vulnerable. So, I dig Moonfire bow’s design is actually good, I just don’t feel we need another one.
So, in the end, in your list, let’s remove “…potential horde application” from Javelin bullet point. What would be its highlights? What would it be doing better than other weapons? Or your thought is to return the penetration while compensating for it by slow reload time? I’m just trying to figure how do you envision the javelin’s modus operandi going forward.
