One of my "The Truth About X" articles, this focuses on comparing Critical Strikes to Expertise. A lot of the anti-Ranger-with-Daggers arguments focus on how Criticals are better than Expertise.

Given

 * The characters in question will have 16 Expertise/Critical Strikes and 15 in the weapon mastery (this is only relevant for the Critical Hit chance).
 * A character described above has a roughly 38% chance to critical hit, and would gain 3 energy each time (using Critical Strikes).
 * A character described above (using Expertise) reduces the cost of skill by 64%, paying only 36% of the base energy cost.
 * The character will use an energy costing attack each time they attack for this proof.
 * For ease of numbers, 100 attacks are used here.

The Math
For Expertise to surpass Critical Strikes in terms of energy management, the following must be true:
 * 36x < 62x + 38(x - 3), where "x" is the energy cost of the skill.

Simplification:
 * 36x < 100x - 114
 * 0 < 64x - 144
 * 144 < 64x
 * 1.78125 < x

The Verdict
As long as the skill costs energy, Expertise is a better form of energy management than Critical Strikes.
