Is it a DPS loss to use macros?

[Arkenne]

The short answer is: Yes.
And the long answer doesn't matter, but its still Yes.

Information about 2.5 rounding up is incorrect. If you switch to a sch and manually cast embrace (which has a 3 Second cooldown) at the same time that you cast the macro to place all your dots with a /wait 2.5 between them your dots will cast .5 Sec BEFORE embrace is ready to be cast again.

Considering it takes a while for embrace to actually register - as do other pet skills... it's register - start cast - end cast so you would likely not notice all the delay.

There is 1 exception, /ac "Flaming Arrow" <t> (and other ground targets, shadow flare, salted earth etc)

Such a godsend this patch.

Make your macro:

/micon "flaming arrow"
/ac "flaming arrow" <t>
/ac "flaming arrow"

That way if you aren't targetting anything or your target is too far away your normal ground target placement will appear.
