I am noticing the immense difficulty difference between curving small trash mobs in a dungeon and a boss. While I feel like I am waaay too far from a small guy curving I see it hit a rank 3. Then I stand for my feeling way too close to a boss and get a rank V. Of-course it is the size difference that makes it feel intimidating 1 way or another. But it seems to be a major flaw.
The scoundrel rank should also be based on the size of the target. Because a very small mob is so much more challanging then a boss to a point that 100s of hours of playing scoundrel still does’t make you close to almost always hitting the curve from rank V distance away.
