I can confirm from a character sheet standpoint that Melee/Ranged Hit Rating factor was altered in this patch to be slightly lower. The Spell Hit rating factor remained constant.
It is possible that the character sheet have the wrong formula on it, you might want to conduct some testing to verify that the actual gameplay value has changed. For example on the PTR for the longest time I had like 1500% increased chance to crit with spells according to the Intellect to Crit conversion cause the factor on the character sheet was wrong.
I can confirm that the value it is stating has changed. I can't confirm whether what it is stating is accurate.
