Barrage
This skill is currently a cornerstone of the most powerful Bow builds, granting unparalleled single target damage once players have found ways to give the skill additional projectiles.
Additional projectiles provide too great a damage increase (as the skill gains 25% more damage for each extra projectile). We don't want to simply reduce the damage of the skill, as this makes the skill much less useful before players have access to additional projectiles.
We're currently trying out a version of the skill that has a base of 5 projectiles per barrage, rather than 4, and reducing the damage to compensate. This will mean that a player will gain 20% more damage for each additional projectile.
4 base projectiles mit dem alten damage = 5 base projectiles mit dem neuen damage. d.h. die neue base damage skalierung ist 80% des bisherigen.
gehen wir mal von bisher 8 projectiles aus: 4 base, 2 dying sun, 1 quiver, 1 helm enchant.
mit dem neuen barrage hätte man 9 projectiles mit 80% des bisherigen damage; 9*0.8 = 7.2; 7.2/8 = 0.9; d.h. es entspräche einem nerf um 10%.
kam man auf bisher 9 projectiles, ist der nerf faktor 10/9*0.8 = 0.8888; d.h. ein nerf um 11.1%.
bei 10 projectiles ist der nerf faktor 12%.
das ist zu verkraften, das ändert im großen und ganzen gar nichts.
