"Funny" macros are just obnoxious and clog up the party chat. If they're paired with sound effects, it's even worse.

Even a normal "Rezzing <player>" macro is useless because if both healers try to swiftrez at the same time, it's a pointless callout; if the other healer doesn't try to rez at the same time, they ought to be paying attention to the party to see if a rez has gone out anyway.

Forget macroing commonly used abilities. You'll become the most hated player in the party, immediately.
