Great patch so far!
Unable to rebind Purge for Shaman units on orc.
Unable to rebind items from the racial shops.
Unable to rebind items from neutral shops which I suspect also goes to the mercenary camps.
Can confirm, purge not bindable is a shame
Found the same issues
Binding the abilites of the Heroes in the Rexxar Campaign is also not working
I perform manual edit of the CustomKeys file to get to remap shamans and other missing keys, and it works fine.
However! Any change within the options (even ticking HD/Reforged) seems to override the CustomKeys file when “saving” the options, resetting the manual changes. Note that this behavior happens even when I don’t change any key. I didn’t try to test to what extend this bug is caused, but it seems that the game overrides the CustomKeys files when it is unecessary (it should only do it in case we remap something within the option).
