Hit Skill Rating Expected Miss Actual
4.50% 0 .5% 0.55%
4.69% 18 0.0% 0.0%
4.44% 18 .24% .05%
3.76% 18 .92% .64% (small sample)
Everything but the 3.76 was done with over a half hour (1800+ attacks) of testing each vs level 70 Haalum.
If what I gather from the rogue thread, 18 skill rating (+4 skill) should give me ~+.4% Hit, not the .32% I'd except according to Crezax, and by comparison, +5 defense from mob level should give me -.5% hit instead of the .2% I'd except from standard defense tooltip. This would change my values to an expected .16% Miss at the 4.44%, .84% miss at the 3.76%, and .55% miss at the 4.95% vs 71's ...
Much closer than my results and within reason considering my relatively small data field. However, I'm feeling fairly confident that the druid base miss is actually 4.9% and not an even 5% As this brings all results thus far within .1% deviation.
