Guide of Modos
You may have just inspired me to give SW another try!. . . After a certain point (generally once a character's parry goes above 7 and their toughness+armor goes above 11), it no longer becomes truly possible to challenge the players in fights without essentially escalating the risk of PC death per encounter above a level I'm not comfortable with.
What I'm hearing is that high(er) level fights are either cakewalks or TPKs, with not enough between.
What is a challenging fight? Is that a metagame reference to PC health, or one with low odds of slaying all opponents? Are motivations and goals involved, or just life and death?
