Your macro syntax is incorrect; that macro shouldn't have ever worked. When specifying multiple conditions (eg. for /clearfocus) for the same command, you separate them with a space, not a semicolon. Semicolons are used for specifying
different actions for different conditions with the same command (eg. /cast [a] x; [b] y; z).
Try this:
Code:
#showtooltip Blood Fear
/clearfocus [@focus, dead] [@focus, noexists] [mod:ctrl]
/stopmacro [mod:ctrl]
/focus [@focus, mod:shift]
/cast [@focus, mod:shift] [] Blood Fear
(I also cleaned up some other redundant/unnecessary stuff.)
