Evidence that Macros Do NOT Cause GCD Delay or Lost Casts

[Shurrikhan]

You have it backwards: players wouldn't be able to use macros if the game wasn't explicitly designed to be able to be played with them. They aren't an accident, the devs added them on purpose, so players could use them.

Though they also seemingly went out of their way to limit them, as certain constraints were added since the rerelease Beta, iirc, and comparable macro systems in other MMOs are not thus restricted. /shrug

For my part, macros seem good for cross-target functionality, allowing a single button to be useful both for clicking on allies and enemies. You give up some queuing leniency for it, but w/e.

More complex functions, though, seem to tend to break down or require an inordinate amount of gimmicking and hotbar space. Which is a bit sad. I feel like the game could simultaneously manage more difficulty and accessibility if it further fleshed out its means of linking buttons to actions in player-customizable --and thereby potentially far more intuitive and efficient-- ways.
