While creating a mod:shift or any mod added macro with the spell Death Chakram. This spell is stuck as primary, and modifiers do not change as intended. If change our Death Chakram for another spell the macro will work as intended, only seems to be with Death Chakram in the macro.
i.e. #showtooltip
/cast [mod:shift]Bloodshed; [mod:ctrl] Fetch; Death Chakram
