You know what is worth your time? Exploration. Can't really do that properly whilst a horde of murderous zombies are chasing you with axes and fireballs.I feel like pretty much everything in souls games has that problem. Bosses give so many souls, and both level requirements and soul drops scale so much over the course of the game that it's never really worth your time to kill anything that can respawn.
Well, unless you "explore" by watching youtube walkthroughs and then beelining straight to the item you were told you need there.
