tanking attack macros

[Zfz]

Dunno, I pre-cast it when the timer on berserk doesn't mark any number and it usually lands on time.

Yep, that's more reliable than any announcement macro. Macro announcement for this is useless spam because the Berserk timer is there anyway.

And to the OP: for tanking macros, announcement macros or even a "warning! <se.1><se.2>" general-purpose macro would be useful. In some fights there are times when the tank have little to do, and watching out for a specific enemy spell cast or skill, then warning everyone by pressing that warning macro, would be very useful. Even the best DPS/Healers sometimes can forget about something and that warning macro may just save you a wipe.
