Realization on Hit Rating.

[Whowantstoknow]

Yes there really is.

You need 6% spell hit to have a 100% hit rate vs lvl 82 mobs. You need 17% spell hit against lvl 83 mobs.

As draenai mages already have 4% hit (assuming not arcane here as they have 7%) You only need 2% hit which is 26.23*2 = 52.46 hit rating (rounded up to 53)

vs lvl 83 you would need 13% from gear so 26.23*13 = 341.02 (rounds up to 342)
