For start, both will only have 2 masteries, cause it will be based on the final cap. I already have 2 other characters which will keep me busy at the 90 and 100 cap

Pure int s/s (bicheon, lightning)
- a lot more damage
- nukes
- speed
- Bicheon skills hardly make use of the points put into strength (a lot less than heuksal or pacheon)
Pure str blader (bicheon, fire)
- A lot of defense
- status reduce
- both magical and physical defense is great
- Uses a whole lot less mp potions
Now, the main thing is, would a pure int s/s still use the chains a lot and would he be a medium tanker (without snow-shield, but probably with a lot of str added on the equipement). I've always loved the blader, but these days it ain't the infinite tanker anymore.
