i was wondering
 

what kind of assassin should i make against all classes i made an asn and i phuked it up and its so damn weak
i got rushed and made another asn

Imo hybrids have been the best cuz of stun lock capability, strong claw damg, speed is a must for any sin, and lotsa life, get enough dex for block and str for a ss, and the rest into vit and adj these to ur equipment and u should be fine, tatics are a bit diff but to sum it all up u need to keep the enemy moving and dont let them get a chance to attack you and use DF to get in close, if u want more info on em ask, im too hungry to type now... time to eat breakfeast........
