EJ said:Hit Rating
Enhance Shaman do not require large amounts of Hit Rating on gear. Effectively, because we can get a large quantity of +Hit from talents (9%), our special attacks (windfury and stormstrike) are already hit capped. All the extra +Hit rating on your gear is going toward improving white damage only, which typically comprises between 45%-50% of your total damage. When you consider the itemization costs of hit rating compared to crit rating and AP, which directly impact 90% of a shaman's total damage, you can see why hit rating is given lower precedence. Take the talents to hit cap your specials, any hit rating on gear after that is icing on the cake.
A common misconception is that you "have to hit before you can crit." This is a fallacy and illustrates a misunderstanding of the attack table. (Note that this is in reference to white damage which uses a single roll system.)
A second misconception is that a miss is a "missed opportunity for a WF proc" and that more Hit Rating will generate more WF procs. This misconception is generated from the flawed assumption that all swings are possible WF procs. However only swings that are outside of the WF cooldown are eligible to proc WF. A good portion of your autoattack hits will never be capable of producing WF procs. A 5 minute fight with no flurry would see 115 white swings with a 2.6 speed weapon. A Shaman might look at that and think that 0.36 * 115 = 41 possible WF procs, but that is incorrect since each successful proc locks out 1-2 hits that follow, shrinking the pool of actual eligible hits. It is actually quite difficult to calculate the number of attacks that you *should* have producing WF in a given amount of time, and that is why we rely on simulators to generate the EP value of Hit Rating.
There is no magic value of +Hit that an Enhance Shaman needs. We need as much of every stat as we can get, but hit rating is just less important than the others. That does not mean that the goal is to have low hit rating either though. Rogues and Warriors require large amounts of +Hit to be effective because of their energy/rage feedback system and because they do not have talents that can hit cap their specials before considering hit on gear. Enhance shaman have no such feedback system and are able to hit cap specials through talents - therefore, hit rating above and beyond your talents is great to have, but is not a necessity.
