We don't talk about Pun-Pun
Knowing the enemy's weak points due to careful study? I'm reminded of a scene from Pitch Black where Riddick examines a skull of one of the aliens to figure out it has a blind spot in it's range of vision, then later exploits it when he faces one.I think this is the issue.
The mechanics really do not display what the lore and concepts mean.
It's either abstracts everything (0e-3e +2 damage to X, 4e hunter's quarry) so you can see what is really happening or shifted to optional aspects (5e hunter subclass, 3e ranger favored feats) so that you don't understand the core.
For example, why does a ranger deal more damage to a dragon with the same weapon than a fighter? Why does the ranger handle the harsh winter's cold better than the cleric wearing the same clothing and armor?
