Would COMBAT_RATING_UPDATE be reasonable event to check secondary stat changes?

[Layback_]

Hi all,

Title says pretty much all.

I am trying to add some features to track and display in text for (ONLY) player's secondary stats like haste, crit chance, mastery, multistrike and etc in percentage as well as it's actual numerical value but ain't sure whether it is reasonable to use or not cause there are about 30 different combat ratings exists in WoW.

Would COMBAT_RATING_UPDATE be a okay to utilize for this case?

Thank you!
