It's been a while since I've played an archer type character, but I seem to remember that 1) the crit cutscene was much rarer than it was for me today, and 2) you never missed when you got that scene. It also seems that archery in general is tougher than it was - I remember one-shotting mudcrabs at range even at low levels, and now I'm throwing a third of my quiver just to put down one crab. That said, it seems like archery in dungeons is working about as I remembered it.
Has it always been this way and I'm misremembering, or has something changed? I actually think it's kind of funny - too funny to be ticked about it - but it just seems weird.
