The comma's function like a pause, if you time how many comma's to include based on your mash speed.

But its a far cry from something like say.... One button press:

/Cast Insect Swarm
- Wait 2 Seconds -
/Cast Moonfire
- Wait 2 Seconds -
/Cast Wrath
- Wait 2 Seconds -
/Cast Wrath
- Wait 2 Seconds -
/Cast Wrath
- Wait 2 Seconds -
/Cast Wrath
- Wait 2 Seconds -
/Cast Wrath
- Wait 2 Seconds -
/Cast Wrath
- Wait 2 Seconds -
/Cast Insect Swarm


The G15 keyboard can be set to click a button, wait so many milliseconds, press another or the same button, etc. That's a true use of a "/wait" command.

The G15 could allow for a decent BOT program, if you took the time to configure it properly.

The comma's in a castsequence only fire off at the pace that we click them.
That's a pretty big difference from a "Wait" command.
