Question about Str/Luk shadowers

I read a thread the Str shadowers are way stronger that luk shadowers due to attack shields. However, my version of maple does not have any attk shields, so would Str shadowers still be stronger than luk shadowers or would Luk shads beat Str ones?

1. Luk Shadowers can also have attack shields, mapleshields / wristguards scrolled with shield watt scrolls.
2. STR Shadowers with the kahnjar attack shields are not -way- stronger then LUK Shadowers, just in the margin of about 5%~10%.
3. Without attack shields or shield watt scrolls, LUK Shadowers are stronger then STR Shadowers, but again, it's marginal...
4. Shadowers remain weak compared to other classes with passive criticals, no matter if they're STR or LUK.
