How good would a 0.0 second GCD Single-Button Rotation delay be?

thats where i say ‘major’ is an issue here…if ‘major’ is defined as “longer CD time” then what about longer CDs that have so little effect on output that they arent worth bothering with? that sounds a little less than major to me.
a major anything is something that has a more profound effect, at least by any normal definition in any realistic scenario.

but this IS blizzard we’re talking about, so who knows.

Factually its irrelevant, though.
I never said ‘major CD’ in the post in question…I said the in game one key will run CDS while macros wont work properly with them, that poster vortimor, didnt bother to read context, he was jjust looking for a one line ‘gotcha’ and failed miserably
