I find this to be even more of an issue since the implementation of 'gigantic' monsters - I used to be able to approximate the distance fairly well (as an archer) to the point where it took minimal creeping up to hit my range. But ever since a lot of monsters tripled in size, it seems like the range got all screwed up (for example, the range to attack a bomb seems to be based on where the center of the bomb is - all fine and good, until the bomb is 6 yalms wide and you have to be right in it's face to get to that creamy nougat center of death.)
