Only one blader in Silkroad could kill us and that blader has Sun+
Anyway about Pure Str or Hybrid Str, well in our server there is one blader-hybrid 80light 20cold, his damage (Silkroad gold) much better than regular bladers, Lightsome points of Int is very good for bladers. All the bladers in our server just failed. Sunners and +8+9 bladers. Most of them changed their own build to light or to other weapon bow/glavie.
We really like bladers. We had one in Cap 90 that is awesome build against Chinese, but barely kill Europeans because when you knock them down. They put cleric shield and your stabs make weaker damage in SRO (Silkroad online gold). Every Str char need must 80% crit on his weapon.
