Uh, the introduction pretty much set the pace with "deep philosophy interspersed with military violence", the escape from the jungle part was pretty violent but it calms down quite a bit after that into a city mafia kind of thing.
It was never Berserk HOLY SHIT CUTTING SOMETHING IN HALF EVERY OTHER PAGE, DEMON GUTS TROLL GUTS SOLDIER GUTS BABY GUTS AND FIRE! then one page of CASKAAAA. Stop wanting it to be nonstop violence.
There is no bad pacing, and you are a fuckass.
