I've been experimenting with macros to remove a few hotkey requirements for a couple of skills i always use back to back (like Savage -> Rage for Paladin, or Thunder -> Aero for casters). The macros work fine, but is there something strange/irregular about the duration of the "wait 2.5" command?

/macroicon "Savage Blade"
/ac "Savage Blade" <t>
/wait 2.5
/ac "Rage of Halone" <t>

That macro works 100% fine but it feels like the wait "lags" at times. Sometimes the Rage goes off immediately, sometimes it feels like there's a 0.1-0.2 second delay. I'm loathed to use them as keypresses do feel simply faster, but is there something I'm missing? Is it purely a visual thing or do Wait commands run off a weird server tick.
