Out of curiosity, how are the Hardcore entries scaled for Story mode? - Is it based on your character's effective level/tier, or are the missions themselves set up for a particular expected player level?
I've been playing through the Story and been doing so in Hardcore difficulty the entire way through, and had no trouble doing so, save for a few missions I only got A or below and didn't get full credit for. Never outright failed a single mission, even got through Profound Darkness without a single hitch.
Through all this I was typically sub-lvl 60, as I experimented a bit and went back and forth on which class to commit to, eventually settling on BoFi which is what I was running for most of Chapter 3 including Profound Darkness. Then I got to the chapter 3 quest at Bouncer ~Lv55*"The Significance of Being here"*, and suddenly I'm getting utterly destroyed by just the trash mobs in the mission; both due to their extremely high damage output and the fact I have to give them repeated vinto combos just to kill any of them.
Is this because I crossed a certain level threshold, and it's now using a different damage model? (ie Super Hard > Extreme hard), or is the mission itself scaled for a higher level character and I should come back later?
