I'm curious to know what makes you think they did not intend for us to run through trash in end game dungeons? From playing 1.0 they made it clear that they wanted you to run through trash and kill the bosses as quickly as possible or you wouldn't make the timer. Heck they even made speed runs part of getting your relic. While I do wish people in DF didn't force the newer players starting off to participate in speed runs especially since wiping at a boss multiple times makes speed runs less efficient than clearing trash. I still have to advocate my support for those of us who can properly clear AK in 20 minutes by following speed run tactics. The number of tomestones it takes to by gear, particularly gear bought with tomestones of mythology you have to spend your time farming efficiently unless you want to take a year to gear out a single class.
