So... basically...
New Javelins get :
-0.5 weight, wich is also
-14% weight
+2 accuracy, wich is also
+2% accuracy
+1 difficulty to a total of 4, wich honestly, nobody cares about since throwers usually have at least 5 PT
-3 pierce damage, wich is
-10% base damage
+2 ammo, wich is
+66% ammo
Balancing Arguments :Why +2 ammo and not just +1, since you're comparing the difference between Javelins and Jarids, with Franciscas and Throwing Axes ?
When heirlooming a throwing item, you don't add ammo, but boost stats. So the difference between the heirloomed old Javelins and the new ones you propose is actually much bigger than looking at the unheirloomed version difference.
Realism Arguments :How the hell can you explain how adding 2 more javelins, all of them having slightly less steel for damage, actually lowers the total weight of that item ?
Just trying to find a mid point between War darts and Jarid
Also if you imagine war darts have the potential for 6x25 damage, at 5x30 you have the same total damage potential. However, it's at a higher difficulty, cost and weight.
Woot ? How can you compare things brutally like that ? Do you know how damage works in cRPG ?
*
My item does 25 damage, so it does 25 damage ?*
If you really want to compare, do it well :
I'm not really knowledgeable about the wpf, so i'll stupidly toss it out. Feel free to post an advanced reflexion with that one, but the result will, i believe, remain the same.
Basic lv30 NoSTR Thrower A: 18 STR, 6 PT : +60% dmg, 163 wpf : + ??% dmg
Basic lv30 FullSTR Thrower B: 24 STR, 8 PT : +80% dmg, 143 wpf : + ??% dmg
*It seems we don't have a throwing damage calculator, so, stupidly, i'll use the melee one (10 PS = 8 PT in bonus dmg), assuming speed bonus situationally helps*
With 25 pierce :
Basic Opponent : 35 body armor : A does 22 dmg average B does 27 dmg average
Armored Opponent : 60 body armor : A does 12 dmg average B does 16 dmg average
With 30 pierce :
Basic Opponent : 35 body armor : A does 28 dmg average B does 33 dmg average
Armored Opponent : 60 body armor : A does 17 dmg average B does 23 dmg average
Quick Maths :
6*22 = 132 ; 6*27 = 162 ; 6*12 = 72 ; 6*16 = 96
5*28 = 140 ; 5*33 = 165 ; 5*17 = 85 ; 5*23 = 115
Unbelievable !!! 6x25 base damage is inferior to 5x30 base damage !
And that means succeeding in hitting the guy 6 times, and not just 5. Incredible.
Quick conclusion : At the moment, yes, Javelins are slightly underpowered.
Then again, at difficulty 3, they're meant to be used in the beginning only. Just like you'd rather use Throwing Axes over Franciscas.
Your suggestion would make them really a bit too strong.
I wouldn't mind adding 1 ammo, and slightly lowering base damage to 30, but without touching the weight and the accuracy. This, in itself, would already be a nice addition.
