Ninja nerfed?

I just came back after 6 months of not playing ragnarok, got myself an airship captain hat, expert archer on grimtooth and archangel wings, bloodied shackle + shackle, and started re-creating the new ninja. Surprise with the newbie guide(i don't like it but still played) got out there at lvl 5 job 10 blah blah blah, let's get to the point

By the time i got my THROW KUNAI, the damage SUCKS COMPARE TO 6 MONTHS AGO, ps : i'm not yelling, just emphasize my point through capitalization. i mean last time i played the damage for a throw is like 2k (fire kunai with undead in payon dungeon) but now it's like 400? WATTT? any possible explanation? i put all in strength btw

i'm a melee build, but i can throw kunais, with 75 str, i did 2k dmg to 175% weaker element monster

mastery is on lv7 and only using eden gear atm (switching to dd would lower the damage, despite bigger weapon atk)

Short answer yes there was a "nerf" to the throw kunai formula but i left RO way before it was really good and came back after the nerf.

yes it was nerf
from start, with 99str with gladius 3zipper+fire kunai, ican shoot Les & wood goblin around 7-8k damage
now,its very very disappointed, only 2-3k damage ,

Not really disappointing to me. It's comparable to the others in it's level range. Plus you'll replace it with kunai explosion anyways.

Its comparable to doublestrafe now instead of being hax.
