In the v5.5.0 Pandaria Classic PrePatch just installed, the following macro is not working for Cat Form Druids:
#showtooltip
/cast [mod:alt] Maim
/cast [nomod] Ferocious Bite
Slotting this macro and activating it while in cat form works fine without any key mod (casting Ferocious Bite as expected), but holding the ALT key to execute the first line and casting Maim instead results in always receiving the message “That ability requires combo points”, even when your cat form DOES have combo points available. Using the Maim skill directly outside a macro works fine.
