oh I see
I have seen a number of questions regarding how the optimizer handles hit rating in classic.
TLDR: If the optimizer doesn’t take you to the hit cap, that’s ok! Mr. Robot is aware of all the math and did it on purpose.
Calculations
Here are all the ways your attacks can do nothing in WoW Classic:
Against a level 63 mob (raid boss)
8%* chance to miss with special or “yellow” attacks like bloodthirst, backstab, etc.
8%* chance to miss with melee auto (and auto shots) “white” attacks when not …
so that 1% hit doesn’t matter, but every % beyond that matters. So ban’thok and star of mystara only matter if you use both, one or the other doesn’t help.
