@bigsocrates: Okay, that gives me some structural understanding. I'm in Act 2 now and it is clearly based around the big war stuff and the particular players are less developed. I like that Leah's mom was not actually fridged as motivation for Cain and Leah. The Enchantress looks ripe for a midriff-based disemboweling, though. Also, shiny things and I love the sentry and raining arrows and gattling gun R2 attack for the demon hunter.
@mbradley1992: Thank you! Essays will always be harder than anything in math ever.
