Fast runs are for mythics. I like that speed isn't as important here.Time is currently being scored completely wrong. Going fast is not rewarded anywhere near enough (max points for speed is 50, and you inherently lose out on way more than that by going fast) and the par times are pretty slow. I got 5 stars on 5 out of 6 of my runs (the one I didn't I managed to get knocked off by the same mechanic 3 times in a row), always just taking my time clearing everything because clearing and playing safe is rewarded the most by far.
This was my first ever run:
Played Shadow, except for floor 4 where I played Holy because I accidentally killed the floor 3 broker before swapping back to Shadow after stacking up my intellect power in the other 2 specs. It's literally just a question of clearing everything, time is basically irrelevant unless you literally go afk.
